I've had my BTA since last friday. It didn't look any different before I left for school this moring but when I go home a few minutes ago, there was a little one right beside it. Is this a good or bad thing. I've read that bad tank conditions can make one split. Everythings seems okay and I think they look alright but I just want to be sure. It just split so sporadicly. I can get some pics if you need or want to see it.
