View Full Version : New tank: Getting worried about all these brittle stars or brittle worms?

Hey everyone. I'm new to the hobby and have a 34 gallon RedSeaMax. I bought the tank from a guy who had been running it for about a year. He gave me his live rock & sand, his water, and couple little coral frags. My tank has been running at my house for about a week. I wanna start adding coral and fish, but I really want to understand how to work the tank before I buy anything. Over the past week, I've been noticing lots of living organisms. I started to notice a whole lot of brittle stars recently, and I do mean a lot? Now, I've been reading up on brittle worms as well, and I'm starting to think, maybe these are brittle worms. The legs that are sticking out have a color pattern of brown and white. One thing I do notice is that where there's one leg, there's a couple more right by it. So would that mean that they are brittle stars or brittle worms? Is it bad to have a lot of these hiding in the rocks? Do I have to worry about a infestation of brittle stars or worms? Is there any type of "clean-up crew" member that I can get, that will eat all the bad stuff in my tank?

Also I started noticing a small, 1 inch long, yellow worm, with multiple stringy heads. There seems to be a lot of them. Any thoughts on these? Are they good or bad for my tank? I think they are called Medusa Worms.

Sorry for such the long post. Appreciate any feedback on the matter.

Sounds to me like you have micro brittle star arms sticking out of the rockwork. They are scavengers and a very good thing to have. Bristleworms are also a good hitch hiker. They eat left over food and detritus. The yellow worm you described is likely a cirratulid worm, also beneficial.

The yellow worm with the stringy heads sound like a spagetti worm to me. Dont worry about them either, they are good for the tank.

any 'bloom' tends to be temporary. Once the population has eaten up what made it 'bloom' it will fall in line with the reality of food availability in your tank. You can solve a lot of problems just by waiting for them to run out of noshies.
