1/4" bug-like creature?

[duganderson]

Hello,

 

I've got a 28 g. mixed reef. I have seen a couple of small bug-like looking creatures that are about 3/16" or 1/4" long cruising around the rock. They are really fast so I never get a good look at them.

 

Any guess what these are? Are they likely safe or an unwanted pest? If unwanted pest, how do I get rid of them??

 

Thanks, Doug

Likely amphipods/isopods. The overwhelming majority are harmless, only a few can be parasitic to fish.

 

Check the hitchhiker identification thread to identify for sure.

Hmm, see if you can catch one with a turkey baster at night. That would be very helpful in figuring out what these are.

+1...What kind of live rock is it?

Yeah Amphiprion1 has some experience with Isopods. Lol

Unfortunately, I do, lol. That's why you definitely want to be sure.

I bought the live rock used with the tank but the owner said it was Figi and Marshall Island live rock..

Are they skinny and long, very fast? I have something of the sort and I think its some kind of isopod. Can't get a good pic to compare though.
