I was at my LFS the other day when I spotted a tank of Thorichthys Aureum. I instantly recognized them as being in the same family as Firemouths, but I have never heard of them before. Gorgeous fish, I was really blown away by them.

I'm pretty sure, I know the answer to this question, but...

Can I add one to my 55 with a Firemouth, Blue Acara, and a Rainbow Cichlid? I know I'm AT/near my max capacity for cichlids in the tank.
