ok i currently have a 55 up and running fine, but you all know how this hobby goes you are never happy. i have always been facinated by the clown trigger. i realize they have to be in a tank alone, but what size tank. what kind of clean up crew can go with them. i'm wanting to put this tank in my room. so if they need larger than 40 or above i'm just going to forget about the entire idea and try to do a nano with a 10g i have laying around. thanks for all the help everyone.
