    Please list all invertebrates which are "NOT" deemed as safe to be in a reef system. Provide an explanation why and your "personal" experience.....


    Don't know about the rest of you, but I HAD an emerald crab that killed, and ate, 2 condy anemones, all my xenia, and was munching on an open brain before I got rid of him.

    Im suprised about the Peppermint shrimp. Camel shrimps (that often get sold as peppermints around here) are notorious for coral munching

    Emerald Crabs !

    i have had numerous emerald crabs, the one i have now is an awesome little guy doesnt mess with nothing and does his job all day and nite, one of the previous emeralds i had did eat a few anenomes but they were slowly dying at the time anyway so i dont think he had anything to do with their demise other then giving them a quicker death critters can sense another that is dying and eat it due to vulnerablility.

    I think this exchange illustrates that there are some species that are on the borderline. I have not had a problem with mithraculus crabs, but I have seen some nice videos of them eating zoanthids. Peppermist shrimp are similar. Some are well-behaved, and I have owned some that were voracious demons. And they were definitely not camel shrimp.

    Also some brittle starfish. I have one and noticed a big decline in my hermit crab population. I found out just the other day that some people who have them said that the brittle eats them at night when it comes out to feed, and some of my crabs looked like they had been half eaten (even my scarlets). Neat to watch but I think hes going to have to go in a separate tank.

    I have had horrible luck with Large hermits eating all fish they can catch.(finally took them back to LPS) He replaced them with snails and a large chestnut cowry. I have had no problems with the Cowry. The other murdering tenants I have (and need to get shed of) are Chocolate Chip Stars, they have destroyed anemonies, small gionopora,shrooms. I hate them with a passion, but my children love them. So I guess nano is in order.

    Let's not forget decorator crabs - I had a fish store employee tell me they were reef-safe once, but you can tell they aren't... Unless you want something to redecorate your tank for you!

    I got rid of my Sally lightfoot. Found my percula in its claws one morning dead. I saw several occasipns when he'd hide under a rock and make a dive at any fish that swam near him.

    I've also had problems with larger blue leg hermit crabs killing turbo snails for the shell.

    Crabs

    I have a small crab (not a hermit crab) which came with the live rock. It started to eat my leather coral. I will trap the crab and throw it to my chickens in the yard!!!

    Never had a problem with the emerald crab, but 3 LFS said orange and purple lobster (cant remember name) were reef safe. Not the one I got, he loves eating corals and wasn't picky about which one either. Traded him in for something else.

    Blue leg kills my turbos

    The larger Blue leg hermits are killers. I have the large Mexican Turbos and when one isn't on the glass, he's fair game for the blue legs. Heard my kids screaming at the tank one day and the blue legs were eating and ripping apart a live Turbo. Looked like fire ants on a carcass carrying parts of the thing back to there homes. Gotta get 'em and send the to the ref.

    Hi,
    I just wanted to add that the lobster you are referring to is just a plain ol' reef lobster or at least that is what they called it when I bought it. I love this lobster, he doen't bother anything and he is a beautiful orange and purple. For a long time he would hide in the rocks but now he is use to the tank and ME so he will come out and greet me a lot more.

    I would have to toss arrow crab on there as a borderline one, did great with all my corals but got territorial with other crabs and shrimp and would go after any type of worm in there, including feather dusters & x-mas tree worms

    I just caught my emerald crab yesterday munching on the last of my zoa polyps (the rest of the colony was previously consumed by hermit crabs). Going to have to get rid of this guy too!!!!
