Which type of cichlid would you suggest putting in with a pair of convicts and a firemouth. i know i want a bristlenose pleco. but i havent decided on what to get yet. the tank is a 55. i also want something that will eat the convicts babies when the babies are older and the parents let them go on their own. i have lot of hiding areas for the babies because i will still want to let a few get a little bigger than the rest.
