I'm looking to add something else to my 150/ It currently houses: 2 Oscars 1 Sailfin pleco 3 Cons 1 Firemouth 1 BR Parrot 1 African Knife I may be moving the knife to my 29, temporarily until it gets larger, then it can go back into the 150. I was thinking of adding a JD, but I'm afraid it will beat up my other fish. What other cichlids would be okay? I was considering a Kissing Gourami, but I'm afraid it'll get eaten. Any suggestions?
