I think that temperature is not that bad 'cause itself but it is the effect that temperature has on air concentration (higher temperature - less oxigen). But more important is that your tank is too small. I once put a proven breeders in a 8 ...

I would like to know how big is your ancistrus female?

The belly was that big that she couldn't attach her mouth to the glass. I was 90% shore that she was going to die but somehow she made it. I was planing her for spawning and now shes useless because the belly is always flat, and I think the illnes afected her ability to produce eggs.

I had a similar situation in my tank. I also have an albino male an he spawned on 10th of july (first time in life) and on july 19th (maybe even on 18th). But not with the same female. In the first one the only one egg hatched and he left the cave after 3-4 days. On the other one (spawning) he ...

12 days after the spawning I saw 4-5 youngsters in the tank. Their stomac was flat, but still, when I moved the cave I found 50 more. Male was still guarding them. So maybe you should start throwing some food at the cave entrance in 4-5 days.

Is anybody in possesion of longfin (albino or black ...

MatsP,

Listen, you don't need to change temp. You need to put the oxygen stone near the cave, becouse eggs need aeration. I had the same situation in my tank. I went on a holliday and I was gone for 12 days. When I came back I found fully developped mini ancistrusses. Their yolk sacs were gone and 50 of ...
