Thanks to everyone that's provided answers to my previous questions. I'm very close to making a decision now on what to get for my tank (it's still being cycled as we speak).

Oscars and JD's are definitely a NO.

I've wind it down to Firemouths or Convicts.

The question is, if I have 2 firemouth males or two convict males in the tank would that provide any consequences? Or is it better to go with 1 male and 1 female? 2 female? Or just ONE male/female in the tank by itself? The tank is 30l,18h,12w and 37-38 gallons

I want to know what kind of characteristics each combination provides (good and bad) before I decided to buy.

Thanks!
