2 uarus are usually fine but if you wanted more you could get away with 3 uarus, 3 severums, one jack dempsey and probably 4-5 cryptoheroes. Just have to be careful when stuff starts breeding because it will if you're keeping that many fish together. Its easier to control if you throw down some tera cotta pots in the corners of the tank. CA/SA cichlids almost always spawn on these compared to picking a random spot in the middle of the tank to spawn. This way their territories are easier to defend and theres not as much fighting because other fish won't go to that side of the tank when they know whats up.
) i would have a green terror no questions asked, mine is amazing and stops fights all the time between other fish (i have read that this is one of their trates which is pretty handy in an aggressive tank). i have just introduced a small jag who seems to be getting on fine as well.
and t-bars but after that im stuck im not keen on angels and geos so im kind of stuck.
