Hi everyone, I got a school of 8 kuhli's a few days ago (2 black, 6 banded) and they are just going NUTS. Glass surfing like crazy. Are they just really happy in my tank or should I be worried? The guy at the LFS said I'd probably never see them all at the same time...well they're all right up front swimming like crazy. Up and down and side to side. They did stop for a few minutes when I fed the tank to eat, but are right back at it. Super fun to watch but not sure if there's something wrong or not. They're in a 29g planted tank and all parameters are perfect. Thanks!
