Is this a cucumber?

jeremygreen · 05/09/2006, 12:19 PM

I found this little guy on a coral that I got today. I think it came in with the coral though I didn't notice it until the coral had been in the tank for a little while so it may have been in my tank.
Anyone know what it is? It looks like a cucumber to me. I just wanted to make sure it was a bad guy...

Certainly looks like one.

Couldn't begin to tell you if it's one you want in your reef or not.

I forgot to say that it's about an inch long.
Are there any bad cucumbers? I figured they all just stirred the sand for you...

If it's only an inch long it could be some sort of predatory nudibranch (or some other form of predatory worm).

QT to make sure (the coral I mean).

It's difficult to tell with the picture. There isn't much contrast to give it shape. It's most likely a cucumber, but there is a chance that it is a nudibranch as stated above, or even a medusa worm.

yes, its reef safe... but toxic if it dies in your tank 1 in a 90 is not bad if you have good filtration even if it dies, but 3 thats taking chances.

It looks like the Cucumbers Ive had...the Local kind here in Fl which are non toxic....Ive lost 2 to the powerheads which are now covered and have never had any problems....they are great sand sifters though and get rid of the brown alge in the sand! I personally Like them...but to each their own!

for the most part all cucumbers are toxic, but some are more so then others

Well, thanks for everyone's replies. It seems that the consensus is that it is a cuke.
It looked like one to me. I just wanted to make sure that I wasn't missing something obvious.
It was a little difficult to photograph given it's small size. It definitely seemed to move like a cucumber rather than like a nudi...
Thanks again!
