Please forgive me if my questions have already been answered. I did do a forum search, and most of my questions were answered but I still have a couple. I got my first corydoras aeneus spawn this morning! I was surprised because I glanced in my 75 gallon tank before work, like I always do, and noticed the corys were absolutely wild! On closer inspection I saw eggs on the tank walls! Unfortunately I had to get to work so I couldn't do anything about it until this afternoon. I was totally surprised to see there were still eggs on the tank walls when I got home from work. I set to work with a razor blade and a plastic fry saver, trying to save as many eggs as possible. This being my first attempt I did drop a few, which brings up my first question. Is it still possible for these eggs to hatch. My substrate is a mixture of sand, gravel, and larger river rocks. Tank mates, if that matters, is one small royal pleco, 3 serpae tetras, one bala shark, 6 corydoras aeneus, and one large liposarcus pardalis pleco. I listed tankmates because I know most of those are notorious egg eaters. My next question is now that they have spawned will they spawn somewhat on schedule? This time I only found about 20 eggs and I want to set up a breeder tank for them. Third question is if the eggs on the bottom will still hatch, should I place java moss down there for the fry? I don't have any plants in the tanks currently, the large common pleco just tears them up anyway, or munches on them no matter what I feed the fat bugger. Tracy

congradulations!, you've got some happy cories.

All the eggs in the tank have a chance to hatch, but of course not all of them will, only a percentage are actualy fertilized. Even the ones that fell still could hatch, you never know.

I leave my eggs in the tank as population control, I don't want that many cories and I haven't looked into selling them to my local fish store yet. They hatch in ~3 days and I can see the litte fry runing around the tank, expecialy after I turn off the light and then check with a torch 15 min later.

Even leaving them in the tank I maybe 1 out of every 200 eggs will makes it to adulthood, so far only one has, but there are younger generations in the tank.(definitly saw 2 last night) I don't know where the rest go, I assume most are eaten by the other tank mates and their parents, but some do make it.

My group seems to spawn every 3-4 days, sometimes its just one female, and sometimes all of them will go at the same time, covering leaves and areas of the glass with eggs. I think they will keep going as long as they are fed and they stay healthy.
