Hello all so have not posted in awhile my son and I were able to give the fire mouth, and green terror to a new home(actually my neighbor) . So now all that is in the 90 is 6 giant dainos, 1 male ebjd, and 1 female jd. Is the 90 good for the rest of their life? Also was wondering of we could do any other dither fish? The 2 jd's have taken to their cave and pretty much like it there. Thanks
