What do you all think of My fish / tank?

when you bought them from the store, did you have anybody helping you pick them out? you shouldn't mix fin nippers in with fish that have big, long fins unless you want them to die. your local pet store should have them categorized by school fish, fin-nippers, aggressive, etc. that's where you should start when picking out fish, then determine the full grown size they will be. at full grown, will they still fit in the tank happily?
