Corals getting eaten?brittle worms and aptesia

[ajn81]

As for bristle worms, just leave them alone, they are great detrivores in an aquarium and as other have pointed out, will serve as part of your cleanup crew. (so don't bother with the arrow crab).

For aiptasia, the best method to rid them in a tank that size would be peppermint shrimp. Not sure they would get along with a cleaner shrimp though.

For those people that get peppermint shrimp for aptasia, they do work well but after time they tend to go after coral. There was a thread on another site that a guy actually seen his peppermint's eating his acans and then a couple of months after I read that I seen mine munching on them, out they went. A copperband butterfly also will eat aptasia and is much more eye appealing then a peppermint shrimp. Problem is they tend to be very hard to get acclimated to frozen or prepared food and often wither away after the aptasia are gone.

arrow crabs have there own set of possible problems like stated so i would look into that prior to buying one.

Aiptasia -
you can use chemicals- be carful and go slow cause it will effect the tank(somewhat effective
shock them- ok but they will most likely come back
peppermint shrimp- works some times. some times it doesn't, as you read above risk with coral
Berghia nudi's- best method IMO but are hard to get around here from what I have heard.
other fish- hit or miss and then other possible problems with the specific fish.

becareful with that arrow crab. He will eat all the little feather dusters, stomatellas, and other little snails.

I don't have any feather dusters i only have astrea snails

Very good to know, so pretty much if i use the peppermint ill have to get rid of them as soon as the aptesia goes away

Do a night check on your tank...hit it with a flashlight after a period of solid darkness. You might see a hitchhiker crab or so. Bristleworms should not be a problem, my tank is full of them, come out at night, clean up crew. Peps good for aptasia, I have 7 along with 2 cleaner shrimp in a 120g cube. Check your feeding maybe its a bit light? Causing things to scavange around more? eating corals?

Just some thoughts..
