LolIt is very amusing watching a crab try to get away from a pincushion urchin intent on picking it up.

I tried to avoid crabs in my tank, but there are spots the crabs are just so good at getting that snails and even urchins can't that I finally gave in. They might take a snail sometimes, but I just didn't see a way to avoid having them.
...I'm sure I'll get a bad one and have to eat my words, but it seems like peeps have an unnatural fear of crabs going after corals. I mean, they cost $4 and are about the easiest thing in the tank to catch. Seems like high reward to very low risk IMHO.
Give them bigger empty shells to go into they kill them for there house.
Crabs are cool to watch but just wasn't worth the hassle. Always crawling on the acans, killing snails for shells when extra shells were everywhere....
...That’s just my observation, snails don’t seem to last too long for me except this 5 year old turbo I have...
I only have a half dozen or so myself, but two of the red-legged ones have really gotten big. One was trying out a medium-sized turbo shell last night. He's not quite ready for it yet, but won't be long.I just bought around 40 hermit crabs. Mainly blue legged. I’m in love with them! They are so cute, and fun to watch! I added some shells a day after adding them and a lot of them changed. My tank is so large, that the tiny ones are difficult to spot among the rock work. I’m waiting for them to grow, and might get some scarlets. J don’t have hermits for a CUC, I have them as pets. They add character and personality.
