I have a 3' 70 gal with lots of live rock that spans the length of the tank (about 100lbs). I've had a starry blenny for about a year and a half who is a bit territorial. Hes about 4 inches long and a chonker too. He always stays at one end of the rockwork where there's a little tunnel he likes to poke out the top of. Whenever a smaller fish like one of the chromises gets too close to his rock he'll chase it to the other end of the tank. He's never actually nipped any fish though. I really wanted a flame hawkfish for this tank but I don't want the blenny harassing it. Has anyone had problems keeping both together?
