Awhile ago we bought a lr from a pet store. Apparently was infested with Bristle worms,which are light pink and about 1/2 in.long, Earth worm looking worms that are sort transparent white and a bug looking thing that is also transparent like. It sorta looks like some sorta crustation. The store we got it from told us that the bristles were benificial but theyve gotten out of hand, you can see them crawling the the sand,ive counted more then 10!! What are good ways to get rid of them? Im starting to worry about our animals. The tank is a 55gal. Animals are: Mardirian Dragonette,yellow tang (which i think need bigger tanks) Two three striped damsels, Lawn mower blenney, Snow flake eel,feather duster some mushrooms and a fire fish and 5 blue leg hermits and 5 turbo snails.
