Good morning all, upon going to bed last night I've found what I suspect to be bristle worms in my tank and have already started thinking about how to get rid of them. I just happened to look in try to locate our peppermint shrimp not no avail. Instead I noticed several worms and these little bugs that move very quickly! I realize this is a very vague discription ( dark brown, little antena's, very very quick, living on the rock) may these be something of major or minor concern? As, I mentioned already were really bummed that our peppermint shrimp we've had for 9 months has come up missing? We have no fish any where near big enough to eat him and they've all been with each other for awhile. Ok, hope to hear from you soon
