Does Coral RX work on isopods?

[Reefing102]

Good morning!

I bought a coral from my LFS yesterday and once I got home, I noticed there were two maroon/brown isopods in the bottom of the bag. This coral is attached to a small piece (about palm sized) of live rock. Will Coral RX work to get any potential isopods left behind? I know it will potentially kill any other pods or other invert hitchhikers on the rock but haven’t read much on effectiveness of isopods

Here’s what I’m dealing with. These suckers are fast and hard to get a pic of. First pic is the isopod upside down, second is no magnification, third is under a lighted magnifying glass(unknown strength)

I've used CoralRx consistently when a buy new corals. So far, it has been very effective at keeping hitchhikers from establishing in my tank. I don't know if it kills larger organisms (including large isopods) at the recommend dose but it does affect them enough so they drop off my frags especially when using baster to move water. I've found isopods, larger bristle worms and bristle stars in the dip water.

Thanks! The two I saw are already out and the coral are currently in my coral holding tank so no ill effect there. I’ll give it a try

Can you test it on the ones you pulled out?

So the one in the pic has already died, wasn’t in much water in the pic and I’m thinking died from evaporation. I’ll have to see if the other one is still alive in the bag (hasn’t been emptied yet)
