I wish I could find a melanarus that was a big baby. I love em.
In regard to the bristle worms, I assume my orange/purple variety feed off detritus? I like when I catch a glimpse of one, it's always a little surprise.
there are a few bad worms, but rarely do we get them in our tanks. most people have bristle worms even if they do not know it, even if you have a melanurus which will keep them in check.
My Malenurus is a big baby & doesn't seem interested in bristle worms. I still see some bristle worms at night in my tank. The bristle worms are excellent scavengers, but they give me the "creeps", especially the big ones.
