Ferreter, try reducing the water changes. I also breed corys and noticed that frequent water changes cause spikes. I would do the changes every 2-3 days. That will give the bacteria in the filters a chance to multiply faster. I too like to use 2-3 filters in my tanks, but I use home made sponge filters unless there is a reason to use another type.
M. clausen – It may sound strange but have a look at their natural habitat. Their food sources come and go, if they eat their own eggs and fry it gives the parents a food source for the times when they don’t have any. In the wild enough fry grow up to keep the species going, it seams like a workable system to me.
Congrats, Make sure the fry are separated from larger fish, the first spawn we had, we used a specimen container (the ones fish stores use that hang on the side of the aquarium), we moved them over, with surface vegetation. We hung the specimen container on the inside (so that the aquarium water could keep it warm), we also put an airstone in it.
If there was a demand for them, I would consider it. There are people on a local forum here that import and ship, even an LFS that has built its business around shipping.
My wife and I are in the process of planning a larger scale breeding operation. Here in the Vancouver area we have near perfect water. Imported fish have problems with osmoregulation in our waters. Locally bred fish don’t have this problem.
I know the feeling about availability, I live in one of Vancouver’s ‘burbs. They are available, but are hard to get. I have started a breeding program myself. While this is actually my second spawn, I consider it my first, as it was the first one I specifically set up as such.

Mine spawned at 23 C .
Try water changes 25%-30% every 2 to 3 days. Make sure the new water is a few degrees cooler than the regular temp of the aquarium.Steve
Here goes. Remember you asked
Inverts
Yellow Shrimp,CRS,CBS,Gold Bees,Decendants of blueberry shrimp
Assasin Snails (soon)Fish
The following Corys
Panda, Pygmaeous,Hasbrosus,Hastatusother fish
Albino Bristle Nose Plecos
Gonna try the following soon (CPDs are a higher priority)Gold tetras, Chili Rasboras
My wife breeds Nano Bettas, and is working on a line of whites
Also the food
Infusora, Banana worms, Micro Worms, Pond snails
wow, that would be impressive to see for real. I wonder how many CPDs you could have in there if it was fresh water

I live in an area with near perfect city water. The problem we have is that fish bred in harder water have problems with osmoregulation in our water. Fish not bred in our water need to be acclimated for a longer period (I always use drip method over several hours), and often don’t survive as long as fish bred in our water.
It is my opinion that there could be several reasons including things like stress, ammonia build up during shipping (3 days is a long time), big difference in PH, big difference in KH and GH, water conditions not ideal for them, etc.
My wife and I do import lots of fish, we always ship them over night, have the shipper email us the PH,GH, and KH on the day of shipping, we measure these parameters our shelves in the water the fish arrive in, and measure the tank parameters of the tank the fish are going into to help us acclimate the fish better.

I don’t see a problem with the Otocinclus, but the Corydoras will eat all the eggs & fry they can find.

Sorry for the late reply. I personally have not observed corydoras eat eggs. My wife and I have successfully triggered the spawning of 3 species of Corys. They exist in most of our aquariums. We lose most of the eggs to fungus. These eggs do “disappear”, not sure what happens to them. After saying that, we have heard of Corys eating eggs including their own. We have not heard of this or observed it for the dwarf Corys.

The tank is a little to small for othe fish, you can try otto cats for the algae, and some dwarf corydoras. The problem is, is that they like to be in groups of 3 or more. This is for both the otto cats and corydoras.

I feed fry on infusura for the first week to week and 1/2, after that baby brine shrimp (frozen baby brine shrimp works too), frozen rotofers work too. I am currently raising fry from 6 different species, java moss works well. The infusora breed in it, gives the fry a constant food source. Make sure you vary the food. Prepared food like baby bites works well too.
I have an infusora colony. I scooped 1 litre of water out of a back yard fish pond, filtered it through a strainer into a small (2 1/2 gal) aquarium. Then added lettice. I kept adding aquarium water every couple of days to increase the water volume. I keep throwing lettice in there. When it is time to feed the fry, I strain it through cheese cloth into a small jar, then use a coral feeder to feed it into the tank. I inject it into java moss too.

We noticed our fry at a very inconvenient time for us. My wife had just got home from work, and I was just heading out the door for my shift. We scooped out the vegetation into one of those containers you see in fish stores that hang on the side of the tank. We quickly filled up a square 2 1/2 gal aquarium with a heater and hung the container on the side on the inside, so that part of the container was submerged in the 2 1/2 gal. We then supplied air with a smalll air wand. My wife also spotted one of our corydoras hastatus carrying an egg. She scooped out as many eggs as she could find and put them with the CPD fry. Four CPDs and 3 cory fry survived. The 7 fry are now growing up together in the 2 1/2 gal tank. The corys are starting to look like hasbrosus (also in the parent’s aquarium). We hope to find more fry soon.
