My corys are in with otos and glolights. My glolights have spawned before as did either the corys or the otos. In the glolights case, I was able to watch the spawning and caught a few eggs with a brine shrimp net, but not knowing any better I put them in a glass jar and warmed the water by shining a desk lamp on them, effectively killing them off. With the other eggs they were attached to some hornwort and I believe they may have been oto or cory eggs but they fungused. I was told that corys usually do not use leaves but the tank wall to deposit their eggs, so it may well have been my otos, too bad they did not make it. And this happened each time after a large water change and feeding grindal worms for 2 days straight. But I did not change the water temps at all. (Well, at least not by more then a little using my hand under the running water method).
But I am reluctant to change the temps by that much fearing the otos and glolights would not make it through that.
My skirt tetras spawned for the second time. They always do this in the morning when I am usually at work but I was off last Tuesday and got a few of the eggs. I hatched them in a breeder net and ended up with 2 fry. Today they did it again (water change last night) and I got a bunch more eggs. I used methelene blue to keep them for getting fungus and I hope a few more will hatch this time. I put the eggs in a 2.5 gal plant tank but there are some snails in it, so they might get a few of the eggs before they get a chance to hatch. But since I really don't want any more skirts, that's ok with me. I am just practising for when my zebra plecos get in the mood, which won't be for at least 6 months, but by then I want to be ready.
