If they outgrow the 125, you need a 180/240/300 gallon. Fish that big moving from a 125 into a 75 won't work out.
COTA has central american cichlids. If you want SA cichlids, you look at Rapps' stock list. Several and Chocolate Cichlids are SA cichlids.
I’ve already reached out to Rapps, waiting to hear back.
I only meant I could separate one or two of the fish out if someone is getting beat on (or one is the aggressor) while I figured it out. I would love an excuse to buy another big tank. Have 180, 125 etc
