now that i have crushed coral base and plenty of river rock i dont know how i want to stock it...the caves arent huge but i arranged it pretty nice with alot of ins and outs from 1 end tank to the other...kinda continuous if u can imagine...should i do a community with like kribs and whatever goes with them or something more aggressive....i like the elctric blues and yellow labs...i like colors on fish for contrast in the tank...i also seen these rusty cichlids i think that looked cool....any suggestions would help alot...i am trying to keep it to the same type of fish that have the same temp. and feeding requirements....oh the tank is 30 gl also....thanks for the help
