I am considering putting(all Juvenlies) a Jack Dempsey, Green Terror, and a Firemouth, in a 29G tank i got for xmas. Would this be suitable for their current size, all less than 2"? My friend has quite a large tank with all of these species living in it peacefully, and i know some say that Jack Dempsey would not be compatible with Green Terrors but i have seen them live peacefully before in a number of instances. Please tell me if these fish would be healthy in a tank of this size. Also are pleco's compatible with cichlids, i would rather have something of the ancistrus species, but finding them is quite hard where i live. Thanks for you help in advance.
