I currently have a 3 gallon pico I'm trying to set up as a pest/hitchhiker tank. I already have aiptasia and macroalgae in the tank and am looking to acquire sponges, asterinas, micro brittle stars, majanos, tiny feather dusters, stomatella snails, random crabs, etc. If you have a cool non-worm or planarian hitchhiker please PM me. Thanks,
