ok everyone my science teacher got a 55 gallon aquarium she loves fish and so far she has an expensive taste. She has a pair of Angels and 1 CLOWN KNIFE!?! ( he is still very small but i dont think they would do well with a 55 ) Also a Jelly bean parrot fish that cost 20.00 she had a big pleco in there but he died ( because some students put some things in there and killed it). The lady at the store said those 4 would go great together. Then the lady at the counter said " Your gonna put those together?"
