I've got close to 30. Its hard to keep track after a while but they're all spread out between a 300, 180 and 135. The 300 is a dedicated clown loach tank which I would like to add some altum angels to, assuming I can ever find some. They're my favorite fish by far and are a lot of fun to watch. My largest is close to 9" and most are between 3-5 inches although I do have a few tiny oddballs with some awesome patterns. One has basically no bars on one side and a normal pattern on the other.
