i recently got a new tank that is 90 gallons and currently it is going through its start up cycle. and i was wondering what fish would be good to put in this tank. i want to have alot of color and personality in the tank and i would like to have one carnivorouse fish that wont kill off all the other fish. i would also like to have a small puffer fish of some kind but im not sure which one yet. i was thinking about sticking with mostly south african style fish but im not set on that. so if anyone has any advice on what fish would go well would be very helpful. thanks
