Sea spider?

[christinna77]

Is this the infamous zoa eating spider? I found it randomly swimming around the tank. I just got a new shipment of corals on the weekend, so I'm assuming it came from them :/ I did dip everything though, so I'm not sure how it was able to survive and stay hidden.

It appears to be, yes!

Thank you! Do you know if they generally stay inside zoas? Because this guy was free swimming near the surface, so I just scooped him up.

Upon further inspection, it actually doesn't look like a zoa spider. They're thicker. But it's still probably not a good kind of hitchhiker I wanna have in my tank.

Just got a response from the store where I purchased my corals and where the spider came from: "It appears to be a zoa eating spider, very common and easy to remove. Usually these drop off quiet easily unless the concentration of the dip is not strong enough".

1. The spider definitely didn't drop off (I used Revive for 10 mins, the concentration was exactly as instructed)
2. It's a bit concerning if they've got spiders infested corals to the point it's completely normal to them.
