I am considering a red tiger mota cichlid or a Mayan Cichlid for this tank and I was wondering if these are good ideas and if I should consider anything else
Unless you plan to upgrade the tank eventually, the Mayan is will grow too large for this tank as it can hit 16 inches.
From what I have read the red tiger mota will grow to 12 inches which again is probably too large for a 75 gal and possibly 90 gal.
Also the red tiger mota is a very aggressive fish and is known to bite human fingers, so know this in advance and be prepared for that aggressiveness from the fish.
I have read that having fish that are less aggressive are boring to watch because they aren’t too much in your face, do you have any experience with that? Thanks.
