I would like to stay with Central or South American cichlids. My downfall is that it is only a 55 gallon tank and SA/CA cichlids get really big.
Not all of them.Just as many (if not more) that never go over 6".
I hate to waste all that filtration and tank on one fish and I'm not a big fan of dwarf cichlids.
Then don't,Try a "peaceful" (well,peaceful as cichlids get) community tank containing Festivum,Keyhole,and smaller Geos if wanting all SA...if don't care use Rainbow in place of Geos.
Can always do a colony of smaller Geo species (some stay around 5" max).
Can always try smaller Pike cichlids (55g gives room for two pair of regani with lots
Been giving real thought to what I'll do with my 55's in the future.One going to the above "community" list,another to Geophagus sp. "Rio Tapajos Redhead" colony,and other to Paratilapia polleni (single fish) once present fish move up.
