So I was setting up some corals today and saw this thing sticking out of my rock. I thought it was one of my brittle starfish legs, but then I realized they were on the other side of the tank.
+1 ^ good members of the cuc can get debris back in the rocks where snails can't reach - their numbers will rise & decline depending on how much you overfeed
Here is what I use to get rid of them. And yes that is a bristel worm not a good thing by far lol.
These work great.
pet solutions online has them, there called (worm trap). sorry wont let me post a link yet because I'm new
A few Bristleworms are a good thing. When they become numerous is when it is a problem. That means that you aren't a very diligent reef keeper. There will only be a population of bristleworms that can be sustained. If there isn't enough to feed the population they will actually cannibalize themselves.
Just limit how much you feed them no need to physically remove them. I used to feed my fish and coral twice a day, but than I began noticing I had way too many bristleworms, now I feed my tank every two days and I don't have so many anymore and everything is still healthy
