Hmmm, I've also read that once the fry or eggs hit the bottom of the tank the male tends to ignore them, which is why lowering the water level didn't make sense. I'm not sure I believe that one though, since that goes against everything else.
I realize the tank size isn't ideal, but it's the best I have available, it's one I'm storing for a relative, the other two of his are bigger.
I was thinking of the bristlenoses because, even though they're small, I thought maybe they'd breed, but at least they'd keep the tank a bit cleaner. Not a big deal though if you guys think I shouldn't risk them?
I'll also need to do a bit of replumbing with the 404 on that tank because it will disturb the surface way too much with the water level lowered. Oh, and I'll need to figure out how to tightly cover the top. It doesn't have a very good glass top. Glad wrap...That's not a bad idea, I might give that a try.
