A starfish, something in a shell and I got worms

So I have found 2-3 small white starfish in my tank. They seem to be eating the algae off the glass and rocks, but I wanted to make sure they aren't going to become a pest.

This guy has been moving around my tank, also eating the crap off the rocks, any ideas?

Also found about a dozen small bristle worms 1 or 2 largish ones at about 4cm long. They come out every time i feed.

Advice, info, flamethrowers are all welcome.

Star fish , always good IMO as long as they have food.

Snails etc, it can depend on ur setup. Some snails are not suited or "reef safe" and some worms can attack corals. Most are ok.

I like hermits crabs myself, but they can. And will kill snails.

That starfish looks like an Asterina starfish. I think they can become a pest if in large numbers. There is a good read at the top of this link that should help you decide on a plan moving forward:

The snail looks like it could be a turbo snail but I'm not 100% sure. If its eating the algae only then it should be okay, but keep an eye out.

Bristleworms are just part of your CUC and will populate depending on availability of food. I think the long, thin ones are fine, however the thick, bright red ones can be the bad ones when they get really big.

Hope this helps.
