What cleanup crew (cuc) inverts do you refuse to keep in your reef aquarium?

What about little blue hermit crabs? They’re innocent and so tiny!

Yes lol. I have hermits too. Let me edit it, the only exception is porcelain crabs and little hermits.

I personally don't have any problem with hermits crabs in my Tank.
I got Blue, Zebras, Red legs hermit crabs, Scarlet hermits. I could said that it took me several restocking until they got a nice balanced population without any predatory behavior for shells, so far so good. At the beginning as they grow they will seek for a replacement shell. I would say that one of them kill a tiger conch obviously in the need for a bigger "RV"... buajajajaja!
But no brainer there, I replaced the conch and life keeps going as normal (all the empty shells stays in the tank, for the next hermit in need) . Sometimes I see them on my corals and gorgonias like picking, but when I pay a closer look they are actually doing their job, cleaning up the area of algae, that the corals and their polyps reside for a while... "Absolutely" . But is a natural response.

For others crabs , I don't have any because, I don't need them at this point in time to balance the ecosystem biodiversity. About Snail , I got a healthy and varied stock of them, from Limpets to Conch and everything in between. Some how with time and patience all of them got a well balanced population, that I haven't restock in few years. Some of them survive the infamous Tank Crash and neglected period, but that's a story for another day.

No crabs for me.
Small hermit crabs are probably the best CUC for hair algae in jagged rock crevices but I don't keep them any more just due to snail predation (even though it never got too bad for me, but still).

Cucumber. I would be worried about one dying and nuking the tank.

Me neither! My new arrow crab hunts them and he is doing a very good job of eating them!

HA! Same..if I can help it!

I love arrow crabs. Its satisfying to watch them hunt and then pull all the bristles off them and eat them! Nasty little critters.

No more emeralds for me. Pithos are OK, they just knock stuff over..

No more sexy shrimp unless I make a nem pico tank. Too many gone rogue and started eating SPS polyps or picking at meat corals. Current sexy is behaving because it knows if it moves from its RFA the wrasses will take notice.

I pretend the bristleworms aren't there. If I see one on a frag or rock I pull, it's gone, but otherwise some unknown cleaning fairy magically comes by my tank at night and takes away all the detritus!
