i was wondering which would be better for my 55? so far i plan on these 1- blood parrot 1- cutteri cichlid 6- congo tetras 3-syno petricola i was going to do just the BP and a medium to large cichlid like a EBJD or severum, but my grandma wants the cutteri. the firemouth seems like it might be better since its smaller, but the festivum is more peaceful. i really like the festivums but i dont know much about them. ill have a lot of filteration, some live plants, and some fake plants to break the line of sight.
