The water I use is a mix of rain water and tap

I guess I should have clarified that my water comes from aged grow out/breeding tanks. Maybe I'll increase the temp a few degrees and see what happens.

And i have to agree with apistomater, 50% survival is not all that bad.

Thanks for the replies.

First off, thanks for the replies. About half the fry have survived. The fry are raised in a large specimen container with about 5-6 inches water and an air source. I feed MW twice a day and perform daily WCs. The water I use is a mix of rain water and tap. The PH is 7, KH 4.

I have a pair of C. Duplicareus that have been spawning since August. Their first spawn ran from April to June. Something strange is happening this time around. After several days of hatching a majority of the fry develop these extended "bubbles" attached to them. They eventually topple over and die ...

My ancistrus just spawned and I was wondering if the 5 ramshorm snails that are hanging out inside the spawning cave will harm the eggs.

Thanks.

Just my opinion but I don't think bbs are harmful to Cory fry per se. I do think that many of the nauplii die and spoil which results in them indirectly causing problems.

Microworms have more going for them as a Corydoras fry food because they sink to the bottom where the fry search for food and ...

Is the other cory in your first pic a C. Kanei. I have three C. Kanei and there some of my favorites.

Congrats on your spawn. My Duplicareus pair have spawned four times in the past eleven days. I've been hatching out my eggs in a specimen container, with an air stone and two drops of methyene blue as an antifungal. Out of 19 eggs I've only had to fungus, and those were added to the container with ...
