its a 75 gallon tank with a satellite power compact lighting setup 4x96.that basslet above the clown is realy giving the mate to this gold striped a hard time. i just bought this female the other day to maybe balance things out but he still is tormenting the smaller male. i might have to move him to my other tank. unless i buy another fish i think i can get 1 more in there. i thought about putting a green chromis from my other tank in there and maybe divert the attention away from the little maroon.
