Got an empty 23 gallon tank with penguin bio-wheel filter and visi-therm 100 watt heater and was looking to stock it with some nice looking fish. I went to my LFS and was enchanted by 2 fish, the german blue ram and the angelfish. I was just wondering, could I keep a pair of angelfish and two blue rams together in a tank this size, or would that be overstocking it? Also, what would you recommend as a cleanup crew for this tank? I was thinking maybe cory cats....*thumbsups
