I am almost ready to set up my 55 gallon SA cichlid community. I am looking for another fish to put with the cichlids that won't get torn up and I read somewhere that bala sharks might be ok. My LFS does exchanges so if the balas outgrow the tank I can exchange them for a smaller fish. The fish will be in a driftwood/fake plant habitat with parrots, 1 gold severum and maybe some convicts. Any other suggestions as to another species that might work would also be appreciated.
