10 invertebrates to avoid

[Rogue951]

I have 3 of thise big hermits in my sump. Bought at Island pets.
they can do all the destruction they want lol. I keep it in the sump in/protein skimmer area and return pump chambers to clean up any crap left over.
one made the mistake of climbing the silicone and up and over the partition into my mantis shrimp partition.... well... he didn't come back out...
