I have a 55 gallon with a Blood Parrot, a Firemouth and a Wood Catfish. Am I just experiencing empty tank syndrome, or is the tank really empty? I was thinking of adding another Blood Parrot, would this be wise? Could I add anything else?
What size is the blood parrot currently? If you can increase frequency of water changes, it shouldn't be a problem although keeping two blood parrots is best done in a large tank even.
I believe you have adequate space for another. Keep a watch and see how they behave to each other's presence. Get another tank ready if they bicker violently as most cichlids have been known to do so.
