Got a HitchHiker - Should i be concerned

[pmcpherson4284]

Hi Guys and Gals !!! Long Time Lurker on the forums first time posting !
Ive had a 75 gallon tank running for 2 months now. me and the wife went to the LFS to get some new Corals and a couple pieces of live rock for them.

Well tonight im sittin in the chair looking at the tank and this big ugly thing shows up ! im thinking he must of been in the rock. I added a picture of it.

I think its a Cucumber, and i was reading that certain species can kill the entire tank if it gets scared or dies.

Is this a Good or Bad Hitch Hiker? Let me know Thanks !!!

Tank setup -
75 gallon Tank, 2 clown, 2 yellowtail Damsels, 1 Foxface, 1 Diamond Guppy.
couple crabs and a couple snails.

Just monitor your water chemistry to my parameters (sig line) and you'll be fine.

Is it a Cucumber?
If it dies will it kill everything?

[Dmorty217]

Yes it's a cucumber, no it won't kill your tank if it dies. Yes they can release poison but not enough to kill a 75g

Yep. Nothing to worry about.
