I have a 65 gallon 38X18 reef tank with a 250 watt metal halide with 2X96 watt fixture. I want to put a firefish in, but was told that it wont do well with a sailfin tang in the tank as well. My fish bioload in the 65 is very low, its mostly corals. Is it okay to have a sailfin tang, kole tang, and red firefish in a 65 reef?
