Inverts that will never be put in my tank again

[whatcaneyedo]

The only good crab is a porcelain crab in my opinion and even they can cause problems so no more crabs period.

Green death brittle star, it never had a chance to eat any fish but it was a bad impulse purchase that now lives in my sump.

Any kind of anemone (including tube anemones). I've only had a couple problems but they arent a good long term member of a mixed reef.

Turbo snails because they become too large and clumsy.

Rock boring urchin because mine kept eating the silicone holding the tank together. It too now lives in my Rubbermaid sump.
