Toxiq Reef Posted October 12, 2013 Share Posted October 12, 2013 Ok I've seen several of these small worms in my tank lately, and it's been untouched for about 6months or so, I dip everything, and started with dry rock.. pics below, what is it?

+Timfish Posted October 12, 2013 Share Posted October 12, 2013 Looks like, or at least some type of cucumber. Anything with tenticles like that around the mouth I would consider a beneficial scavenger. Link to comment Share on other sites More sharing options...
Toxiq Reef Posted October 12, 2013 Author Share Posted October 12, 2013 Thanks, they are skinny and can stretch quite a ways, not very large however Link to comment Share on other sites More sharing options...
Toxiq Reef Posted October 12, 2013 Author Share Posted October 12, 2013 also they generally hide in the light Link to comment Share on other sites More sharing options...
Wade Posted October 13, 2013 Share Posted October 13, 2013 Aren't cucumbers risky because if they die they poison the tank? Link to comment Share on other sites More sharing options...
+Timfish Posted October 13, 2013 Share Posted October 13, 2013 Some cucumbers have the nasty habit of eviscerating themselves when they get stressed. Some can be quite large and it can be a shock to the ecosystem when this happens. The species that crawl around scavenging I haven't had any problems with and have and some reproduce successfully.

Toxiq Reef Posted October 14, 2013 Author Share Posted October 14, 2013 Here are more photos, poor quality, sorry. There are roughly 10-11 of these that I can see and count, what might eat these things? It's about impossible to pull them from the rocks Link to comment Share on other sites More sharing options...
bige Posted October 14, 2013 Share Posted October 14, 2013 Looks like one to me. Mine stay in the substrate. I wouldn't worry too much about it. It will probably hide/retract when lights are on. Link to comment Share on other sites More sharing options...
