I have a 125 gallon tank with 9 Angels, a Baby Whale, a Ghost Knife and 2 baby Severums. I want to move my Pair G. Geayi into this set up so I can use their tank for my VERY aggressive Micropthalamus. He can 't stay in his current tank any longer. Way too aggressive. Most of the fish in the 125 are small with the exception of 2 Angels which are about 4 inches. What do you guys think? I could eventually thin down the Angel population.
