Hey all, Today I started my tank re-vamp. Am re-doing the sump as I speak. My tank is known to have a few brittle stars, one is particularly big and has lived inside a rock on the right for about a year, never caused a problem, even with other cleaners/ inverts. Earlier, I went to the LFS and got two really awesome medium sized cleaner shrimp ($155 AU each) and a clam and anemone. Whilst cleaning the sump, I noticed, hey my shrimp seem to be missing. I look over and they are basically in the mouth of this bristle star. It killed both of them. I was so pissed I took the rock out, smashed it up and killed the bristlestar. Next bristlestars I see in my display will see the same fate. Kill all bristlestars.
