My experience with firemouths has been that they are slow growers. Turn the temp to about 82, add some beefheart to the diet. Will help it grow faster if thats what you want. Here is some info:

Aggression
This fish tends to have a "live and let live" attitude to it. However, it can be quite the bully when housed with a fish it doesn't like. This fish is quite capable of taking up for itself without becoming hyper dominant.
