Hey gang. I really have no idea how old they might be. The guy I got them from (BriansTropicals) back in Jan or Feb. says that they are really small when they are born. And these are now, like I said, about 3/8". I have them in my community 46 bf, with an emperor 400 and an AC 70 for filters that provide the flow. I have lots of caves and slate, lots and LOTS of company in the tank (waaaaay overstocked, H3D would be proud !), and I actually keep the temp a little higher than recommended for these guys (78°-80°). So needless to say, I was quite surprised to have fry. Now I have to try and see if I can figure out how many are in the tank, without breaking down the tank completely (which I am NOT gonna do !) Here's the tank. I'm sure you've seen this pic before.
