New Fish

[jdp95]

I have a 75 gallon tank with a red devil and jack dempsey both fairly small (3-4 inches each), I am looking to get a new fish. Any suggestions?

keep an eye on aggression as they get bigger, dont know if theres a whole lot of room for more fish in there, could be worth adding a school of 8-10 giant danios to try to divert aggression
