I decided to make this post to list the hitchhikers I have in my tank, because I keep finding new ones Hopefully I can snap a few pics, but I can't make promises For the record, my tank was established in April or May. Ball anemones Bristleworms Brittle star (brown/black, 15+ of them) Pods Stomatella (white and black ones) Ball anemones: I (foolishly) thought I only had one, so I had squirted it with lemon juice, and thought that that was the end of it. However, doing my regular night watch on my tank, I did some closer looking, and found out I have 5+ spread out over 2 rocks . I'm going to remove them and scrub the rock with a toothbrush when I get home this afternoon Bristle worms: First noticed these and was pretty grossed out! However, I've gotten used to how ugly they are. I found one that was about 4" long, but still pretty skinny. Since then I've seen a few more. Brittle star: Found one of these guys and at first thought it was a spider in my tank (I could see the whole body at the time)! That was months ago, and before I had moved my tank. Now I've noticed their little arms creep out at quite a few places. Pods: Well, not much to say about these. I've had an abundance of them lately, and some of them are pretty big! Makes me wonder what my goby does all day.... Stomatella: I was surprised when I first saw this white half-shelled snail. They're pretty odd-looking, but they're pretty fast movers (though not as fast as my bigger snails). And then last week I had found a black one! After a quick search, I saw that the black ones were harder to come by, and felt pretty lucky that I had one. :thumbs_up Hopefully they breed with the white ones?!
