The Barb Keeper
Aquarium Advice Apprentice
Often I see the holey rock and cichlid used in the same sentence. I know cichlids prefer harder water . I also know my barbs could handle a harder water as well. Thing is my Barb tank is set n I like it how it is. wondering what other fish people have successfully kept with holey rock,any insight is welcome. I can get a whole mess of it for 20$ thinking of grabbing it regardless but I'm curious.
