Here's a representative sampling of my ~ 40 gallon 'fuge, which has an overabundance of apparently prolific tiny tiger-striped brittlestars. Does anyone have these, and do you have them in huge numbers? I don't know when they hitchhiked in, but they've made themselves at home. They don't move around much, and they don't bother anything. I just wonder what it is that they like so much in my tank.
