Okay, so I removed the java moss that was literally covering the tank from top to bottom. It stirred up a bunch of gunk, so getting pics after I did that is pretty much impossible, but I will try again tomorrow. I have a better idea of how many are in there now, it looks like around 50-75 or so. There is beginning to be a size disparity (primarily because there is 2 different spawns in the tank) so I'm slightly concerned about predation, but haven't seen anything yet.
