Thanks guys
BV, to be honest, I have no idea hold old they are at this point, lol. I can't remember when they were born (I really should get into the habit of keeping track), but they're at least 5 months now I would think. Originally they were kept in a breeder box until they were big enough to go into the growout tank, which was a 20gal long, where they stayed until about a month ago. When they got big enough, I moved them into the 55gal community tank, and they're doing really well. The extra space seems to have given some of them a growth spurt, and a couple are starting to get to a decent size for their age.
