i wouldnt really keep rams n firemouth together as firemouths get aggresive esp in small tanks 3ft n less
rams should be kept in softwater
There are coloration differences, however, depending on each fishes place of origin.
"Known as a or the "Beginner's Cichlid" for its wide tolerance to conditions, Firemouths are fine in most any source of tap/mains water. What does make a difference in their color and breeding behavior is temperature. These are tropicals that really appreciate warm water (see above). The low to mid eighties is fine for them every day, with a few degrees warmer for stimulating spawning.
As you might assume, after being in captivity for so many generations, this fish is very "plastic" about what it will accept in the way of foodstuffs, and it is. A staple diet of large flakes, pellets and sticks is fine, as long as it is augmented with occasional offerings of more meaty fare. Earthworms, bloodworms and shrimp are especially relished"
