Question about a Hitchhiker

[tomstechnic]

I went to the LFS today and bought what I thought was just a rock with a soft coral frag on it. When I got it home, I found several hitchhikers... 2 were good, a snail and an emerald crab. The third was a cucumber. Here is a picture:

I am quite new to the hobby, and would like some advice about this critter. I know they are toxic if they die, but I guess I am more concerend about how hard these guys are to take care of.

The other critters that I have in the tank:
Clarks clown
Yellow Tang
4 blue/green cromis
banded coral shrimp
skunk cleaner shrimp
serpent star
emerald crabs
assorted hermit crabs and snails

Any Help would be greatly appreciated!

that cuke looks like its from the Holothuriidae family. they are sand sifters, and usually wont hurt anything even when they die, as long as some thing doesnt ingest the cukes flesh that is. if they get sucked into a powerhead, they could cause some major damage to the tank as most the corals and fish will eat or attempt to eat the flesh in the water column. other than that not a real threat to cause any toxic problems.

Definitely not a sea apple you got, but by the coloration it doesn't look like a tigertail either. Tigertail and black cukes are the least toxic. Just keep your eye on it and don't let it get caught in a powerhead either. I've had a couple of tigertails and they were excellent cleaners.

Thats great news. My powerheads have a foam cube covering the intake. Learned that lesson already. Had a cromis that got sucked in and died soon thereafter.

Thanks for the help!
