i have 2 kuhli loaches right now and "was" planning on getting 4 more, but then i keep having thoughts about corys as well. so i was thinking about minimizing my selection to 4 kuhlis, but then again i would only have enough floor have for 5-6, is that an okay group? the tank is a 46gal community tank btw.so would adding both corys and kuhlis be over crouding the bottom? i am planning on heavily planting this tank as well, so plenty of hiding spaces will be provided.
