ask yor LFS if they can order some rock for you. if they are selling african cichlids, they already have a customer base who will buy that kind of rock.
Thanks for more information guys, I did have another question. Everything i read says to have a 2nd tank to put the females in when they're carrying the fry in there mouth.
What size of tank is required for this at the minimum?
pic the cichlids you prefer, if you prefer CA/SA then pick which ones you like, if you want african make sure to have lots of rock work and probably more fish to spread the aggression
