The first one is a brittle star.
Mini Brittle Star fish, in the sink. Feather Duster tubes, on the pump. Both are a great part of your clean up crew. Brittle Stars eat detritus and the Feather Dusters filter the water.
dammmit i guess throughing him down the drain was not a good idea, he was stuck in my pump anyways and i have several of these damn things in my tank anyways haha
