I was thinking of buying a coral banded shrimp to try to get our bristleworm population down to a manageable number, but that tank is a 45g & has 2 yellow & 2 green clown gobies and a bi-color blenny. I've not yet talked to anyone that says the CBShrimp is actually mean or aggressive, but I've not spoken to anyone who wants to say he's not either. I did search the archives here & see several posts about the CBS being very agressive to other shimp, but we don't have any other shrimp right now. Does anyone have personal experience with a CBShrimp w/such small fish as the clown gobies? I would probably only keep the CBS long enough to do some cleanup, but I really don't want to risk him hurting my gobies...I love those fish!..SO cute!
