Hi, I'm new I just got back into the hobby I got a 20 gallon hex tank its finishing cycling with 2 dwarf gouramis and 2 female bettas. However I have hard water and a lot of fish don't thrive in my water even with ph adjusting agents. But ive researched and Cichlids are supposed to like hard alkaline water and are great little fishes. Any suggestions on a smaller species for my tank would be appreciated
Thanks
