I'd recommend them with barbs, haven't tried with angels. With fire mouths I'd say the acara would be dominant, mine used to handle my convict easily; and control aggression.I have been thinking of getting a blue or electric blue acara, for those of you that have them. Would yall recommend them in a planted tank with angels and barbs? It's a 105 gallon tank, trying to stock it and looking for ideas. I have thought of a few blue acara with a few firemouths. Not sure how they will handle each other.
Definitely worth tryingLooking for less aggression and color since it will be the main tank in the room for now.
