Bug on dead fish

[ethanbear111]

This is a yellow clown goby I bought yesterday, it was shy when I got it. I drip acclimated it and another yellow clown goby for about five hours, and the other one swam around the tank while this one hid on a rock. I wasn’t sure where I should post this, because it doesn’t seem like an immediate emergency. It’s gill seems a bit puffed up, and I think it was a bit puffed up yesterday.

It is dead just to clarify.

That appears to be a cirolanid isopod.

They are predatary to fish. It's possible it was hidden within the gill when you purchased it. Hopefully that was the case and you don't have more in the tank. Sorry about your goby, but good thing you were able to get it out of the tank with him.
