Now whenever you walk into a pet shop you find almost a hundred different kinds of fish its a fact that all are unique but stunning creatures. I have had a multitude of pets and still have but my tropical fish live with my 2 turtles and get along fine for 1 simple reason the fish are bigger although they are oscar fish and plecs. The main thing to remember about tropical fish is can they get along with each other? For example i re homed about a dozen angel fish they were fine a month then when i got home from work 1 day they had all savaged each other found out later it was their breeding season and 1 of them was female so you must check with the seller and research them on the internet for the requirements of the fish and their breeding season habits do they get violent? Can i separate them if needs be? Remember not all species go together but most tropical fish are community fish and best kept in groups of their own species or similar. Pets are for life not a few weeks remember.
