Every death I will remove it instead of letting it tear apart by others as I do not want the water to be damaged. The tank have hundreds of blue bolt shrimps from original batch of 7 which likely comes from 3 parents. </p><p>Each of the day I will add Stability and some Prime with reduce dosages. Per instruction New Tank requires 7 days of Stability. Not taking chances. I have been adding about 2 to 3 times a day of reduced dosage.

I bought 9 blue bolt shrimps from the internet. They are really small. Takes long time for them to grow up.<br />
Ended with 5 adults. Recently I accidentally lost 2 of them. Suspect they have themselves hidden in my air filters and got washed out into the dirty pail water ..... darn ...<br />

I was doing major overhaul and introduced black water due to recent water quality issue. To my surprise, a day later I found 1 of the 3 surviving shrimps is berried. The other two shrimps are males.<br />
<br />
Hopes to see the shrimplets survive in this corydoras tanks.<br />

Winter has passed. The weather getting warmer and I think is time to scrub my glass from algae. I also decided to move all my Corydoras into a single 2ft tank for easy maintenance.<br />

I have another air filter moved over to support the increase loading despite many of the red shrimps have disappeared due to acidity of the water from the Indian almond leaf. In total I have 4x duplicareus, 6x virginiae, 2x sodalis, 5 atropersonatus, 4x sterbai, 10x elegans. That's the max I would go for now. I like them so much.<br />

They look very healthy and reasonably prized. Requested for two initially but decided to get another two more on impulsion as I seldom see them on sale. I would love to get more but I think maximum i would allow at a time has to be limited to avoid water quality issue.<br />
<br />
Probably will consider two more later once this batch settled down. One of them got caught in the net and the shop assistant has to manually handle it in order to remove the pectoral fin from the mesh. I could hear the rag sound which seems quite loud when separated. Likely serrated.<br />
<div>
<br /></div>
<br />
The translucent white on the body frame looks clean and nice. Faint Black lined the top edge of the body. They swam in group immediately and their size are relatively large. Beautiful fish. According to ScotCat web site, is a hardy species of corydoras so I am glad to have purchased four of them.<br />

I am back on this species. Just acquired 3 of them from the famous fish street in Taipei. The aquarium store provides professional service. The fish is bagged individually and double bagged with newspaper in-between. I am please with their knowledge.<br />

The species I got is the higher torso variety which I preferred. The shop marketed it as wild caught. One of them have dark botch on the dorsal. On the coloration or pattern, my criteria is to look for thicker black band sharper cut.<br />
<br />
<br />
Above picture : The background is not so good. I would get a darker color in the future for fins clarity which will help to identify the sexes. The body shapes are not clear as I feel it needs to be fed for some period first to be more definitive.<br />

<br />
Above picture : I did not do acclimatization as the bagging is good and the fishes are healthy. The longer time they stay in the bag may not be a better option. So I just scope them up for the plan view taking and immediately release them into the community tank.There is some rapid gills movement in one of them about an hour. Other than that everything looks normal after. I do some feeding and roughly 15% water change next morning just to keep them fresh.<br />

Looking from the side, trying to take care of both front and back view since i like people to view it from both sides of my table.<br />
<br />
Bottom right is the bubble counter. Filled up with filtered water to avoid deposits.<br />
If done right, water inside will remain for long time. So far 1 week already.<br />
<br />
Top is the 2 FT LED lighting. Not sure enough. Will continue to monitor.<br />

Has two pressure gauges with solenoid. I like the ease of setting them up. Did some fine tuning to understand how they work.<br />
<br />
The left gauge of mine reflects the cylinder pressure with a lower valve to control it. Open more than enough for it to flow.<br />
<br />
The right gauge again on this cylinder, reflects the pressure to the bubble counter. Controlling the valve just below it manage the bubbles. there is some lagging to watch.<br />

<br />
Here's the reactor. I was a little worried that my overhang filter is not strong enough. However looking on the direction of the bubbles moving across from the bounce back current coming from the opposite end means the flow covers the entire area.<br />
<br />
Fitting in the CO2 tube is a challenge as the pressure keeps pushing it out. Finally uses drastic measure of heating up the tube and freeze the reactor to tight fit them. Follow by a lighter across the overlapping areas.<br />
<br />

Picture with plants. I got 3 mat size of the plants, cut them up to smaller pieces and squeeze them into the gravel. One thing i should have done instead is to wet the gravel a little instead of filling up to an inch. Will be much more easier to hold down the mat into it.<br />

Thinking of setting up a shrimp based planted tank. Spend 30 minutes to blog and research my plan.<br /><br />One key takeaway i found is the need to be prepared to acclimatized Shrimp as they are sensitive to water conditions.<br /><br /><br />My Notes : Planted, CO2, Small-Medium size tank, Plants, Shrimp species, Fish types, Tank layout, Food, Lights, Soil, Shells, Mini Net with long handle, external drip hanger, Wood/Stones, Mini Canister,Scissor - 14" - Curve, mini-net.<br /><br />Few things to watch,<br /><br />
<span style="font-family: inherit;"><b>CYCLED TANK</b></span><br />
The planted tank has to be ready and stable before buying Shrimps<br />
<div>
<span style="font-family: inherit;"><br /></span></div>
<span style="font-family: inherit;"><b>INJURY</b></span><br />
<span style="font-family: inherit;">Netting rims are hard and pressing the shrimp against the plastic bag can cause injury</span><br />
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;"><b>STRESS</b></span><br />
<span style="font-family: inherit;">Avoid transfer that expose the Shrimps to air</span><br />
<span style="font-family: inherit;">Especially when they are stressed. </span><span style="font-family: inherit;">Moss to calm the Shrimps</span><br />
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;"><b>ACCLIMATIZATION</b></span><br />
<span style="font-family: inherit;">Spend an hour to transfer tank water to the shrimp</span><br />
<span style="font-family: inherit;">Do not transfer water back to the tank to avoid external introduction</span><br />
<span style="font-family: inherit;"><br /></span>
<b>SAFETY</b><br />
Shrimps molt when environment parameters change. During this period their skin is very soft.<br />
Remove fishes that will attack them.<br />
<br />
<b>FOOD</b><br />
Do not feed them till they have settled comfortably<br />
<br />

Three more deaths from different hatcheries but none of them has red content in stomach from the red coloring of dry foods. I decided to stop Brine Shrimp feeds (maybe is too potent) just in case as many of them able to take dry foods already.<br />

</tbody></table><b>Oil Accumulation</b> on the surface is another issue. Interestingly there is one hatchery that do not has. In it, there are frys swimming upside down suckering on the surface which probably explains the lack of it. Not sure the extend of impact to their health. One of the DIY hatchery was then modified to allow surface pass through with the main tank as an experiment. This is fun.<br />

Finally after a painful number of corrective actions, got to see the stage of free swimming frys eating external foods. Death rates have came down significantly to almost zero. The frys are much stronger and vibrant as well.<br />

To date, i have at least 20 free swimming frys taking both brine shrimps and dry foods from 3 different hatcheries of different batches. About another 20 still taking york sac. And about a dozon left over eggs. Since cutting down on food to the adults, breeding has slowly ceased. This allow me breathing space to concentrate of growing the frys and a cleaner tank water.<br />

<br />
During this period i have the hatchery expanded to cater for larger active frys. They are handmade of which the design i am proud of after many trials and errors. Is more fun than keeping the frys alive though the result is the goal.<br />
<br />
<br />
<br />
<b>Hatchery Requirements</b><br />
<b><br /></b><br />
- Will not topple<br />
- Prevent foods from slipping through<br />
- Side and under opening to support good ventilation<br />
- Shock absorption internal and external<br />
- Will not escape or eaten through gaps<br />
- Easy to navigate the hatchery<br />
- Easy to observe the frys<br />
- Large enough room to support fry growth<br />
- Cheap and easy to access materials<br />
- Provide shade but avoid dead corner area<br />
- Tank debris not easily stuck onto it<br />
<br />

To my surprise, all my corydoras were quite afraid of it and keep themselves onto the other side of the tank. The juveniles will play around it but will not dare to step through the tunnels. I saw a foraging adult get spooked at the entrance when it unwittingly explore to the entrance and make a quick getaway.<br />
<br />
This is incredible ....<br />

This batch of frys have high losses ~ about 75%. As now only about 6 lives on Day 13.<br />
Few areas which i have taken note to improve subsequent batches as i re-learn ....<br />
<br />
<b>Issues with Frys</b><br />
<br />
1. Infertile Eggs<br />
Inexperience young female<br />
<br />
2. Insufficient Eggs Collected<br />
<br />
Likely eaten by other species of corydoras like C. atropersonatus who is known to eat their own eggs. I have seen a dying fry got eaten up today when i let it down into the main tank.<br />
<br />
3. Dies inside it's shell before hatch<br />
Occur in my first batch. Suspect too early retrieve of eggs and fungus.<br />
<div>
<br /></div>
<div>
4. Anti-fungus solution</div>
<div>
Not really effective and eggs still go bad.</div>
<div>
<br /></div>
<br />
5. Unable to detach it's head from the shell.<br />
Do not attempt to help remove it. At this stage the fry is very fragile and may cause more harm.<br />
<br />
6. Fry refuses it or swirl around<br />
Brine shrimps are not clean enough from salt. Rinse many many times.<br />
<br />
7. Blood streak in the stomach<br />
Looks healthy but will die suddenly. Suspect constipation from brine shrimp eggs.<br />
<br />
8. Weak Frys and turn white<br />
Suspect poor ventilation. I moved the floating hatchery nearer and ensure the sides are open to flow.<br />
<br />
9. Feed too early<br />
Will wait till Day 11 next time for closer observation.<br />
<br />
10 Major water change<br />
Even on main tank, 50% seems ok and will not impact frys. Cutting down on food to the adults will help.<br />
Daily changes even small amount may helps.<br />
<br />
11. Day 14-17 period, Frys are truly free swimming and observed to eat external foods.<br />
This may mean prior weeks to avoid feeding unless necessary as rotting or fungus foods will weaken the frys.<br />
<br />
12. Oil formation on the the surface<br />
Hatchery without it tends to product more active frys. Just enough floating plants and ensure near to filter turbulence will minimize their formation.<br />
<br />
This list will be updated subsequently.<br />

There is two long sink-woods interlocking with some bush plants.<br />
<br />
The wood underneath is a favorite place for them to hide when i am busy with the tank.<br />
<br />
Air bubble pumps are used. Not in picture is a 58cm LED light on a timer and an auto-feeder hooked up.<br />
<br />
<br />
<br />
<b>Tank Two :</b> Another two-feet tank with two small pieces of sink-woods separated. Is a breeding tank currently and able to take a lot of punishing fish load so far. Some moss over the surrounding area and floating plants on top.<br />
<br />

<br />
After incubating for days, they hatched on 5th. Photo is the 8th day.<br />
<br />
Their bellies are getting smaller and is time i try to start feeding them some live brine shrimps. They are not eating yet but i hope in 12 hours time.<br />
<br />
While I am doing all this, i have already collected about 3-4 batches of dozon eggs each time during this 8 days period. The batch size is a bit small as they are known to lay about 50 eggs a time..<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh7Q2XBBVDWbNgF1-VfpNd9ohK8VQlwGfakW0f_5GvcZXLzVTA-Ef_wsOndJ7ff8gQoDz1j529bU3v9MzsrjlF6tVfzZ5NKcISY5EuvsoyD6PUZMgTY9fJVh9ILasPoDj1cjUuefzeMQ1fq/s1600/C.+duplicareus+eggs++20120423.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="212" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh7Q2XBBVDWbNgF1-VfpNd9ohK8VQlwGfakW0f_5GvcZXLzVTA-Ef_wsOndJ7ff8gQoDz1j529bU3v9MzsrjlF6tVfzZ5NKcISY5EuvsoyD6PUZMgTY9fJVh9ILasPoDj1cjUuefzeMQ1fq/s320/C.+duplicareus+eggs++20120423.JPG" width="320" /></a></div>
<br />
Anyway I have the different batches separated into a number of hatcheries till i ran out of space and decided to move some to the guppy mini breeding plastic box on the left photo.<br />
<br />
However the slit holes are only slightly smaller than the fry on the first day. Once the bellies start reducing, they will easily pass through them and fall down to the tank bottom which is almost a death sentence to most frys. Therefore do remember to move them out once hatched.<br />

One infertile egg of the dozon which is quickly removed to avoid fungus from developing. Depending on temperature, the eggs expect to take about 5-6 days to hatch.<br />
<br />
The next challenge stage is to maintain the water quality as frys are vulnerable to nitrate build-up. Therefore I will have to cut down my feeding to the adults below. During this period which last a couple of days, the frys do not have to intake external food. Their large belly has nuitrition to keep them fed.<br />
