So Ive had this tank set up for 7.5 months, it's my first foray into salt in around 20 years. Bought a hammer a few months ago from a shop that told me I didn't have to worry about a dip with his stuff. Lo and behold, a few months later I've got critters. These two I was able to get shots of, and I was hoping for some I'd help and, possibly some help in control other than cutting feeding, maybe a suggestion of a predator for them, particularly in the case of the worms. The bug type (copepod ?) Is tiny, don't even see them most of the time. The worms are abundant and getting larger in size. This is a 10 gallon with just a small pair of clowns and a few snails.

First one bristleworm. Second photo is a munnid isopod. Both are beneficial members of the clean up crew.

+1 On the Munnid isopod. It is harder to tell for the worm without higher-resolution photos, but it might also be a Dorvillidae worm, a beneficial grazer.
