yeah i have 2 or 3 of them that came in on the live rock over a year ago, they were the size a a quarter then, they are less that the size of a half dollar now
bristle worm in lower part of picture. i don't know how big is to big, but i started seeing one or two the past couple months, so i was going to set up a trap so i can try and estimate the size of the population in my tank and go from there. i don't expect many, but i want to be sure.
Those are all a little ones I have one that's bigggg like it's the size of a 50c piece lol and I was getting worried because I had a magician die and my purple people eaters are closed up and they both had sponge near them so I am worried about it i cut it away from them but they still wont open btw Doug those dragon eyes are doing great the always open
