Do you know this parasite on my fish ?

[quentin17110]

Hello everyone

I introduce a new flame hawk fish in my tank and I discover he had a parasite on it.
I was able to catch him and remove it.
Here is a picture of it.
Does someone know what parasite it is and what to do ? Should I be worried to my other fish in the tank ?
Thanks in advance

Sorry - not clear enough to tell for sure. Might be a isopod. Was it moving?

Yes it was moving

The two common external parasites are isopods and copepods. Either way, they have complicated life cycles and usually have specific hosts, so they don't typically spread in home aquariums.

Ok thank you sir.
It feels like my goby got infected too but impossible to catch :/ should I leave him like that or is there anything to do ?
My wife will take a picture under microscope today of the parasite, I will share more picture tonight

Yes - better picture might help. In the meantime, here is an article I posted on arthropod parasites of fish:

Seems like a fluke right ?

Yes - that is Neobenedenia, an egg laying fluke. They are tough to control because the praziquantel treatment, although reef safe, does not kill the eggs. That means you need to do multiple treatments and try to kill the flukes as they hatch, but before they can lay new eggs.

In a fish-only system, these are best controlled with 35 days at half salinity.

Right now in the tank I have star fish, brittle star, snails, anemone, crabs, 3 Chromis, 2 clownfish, 1 goby, 1 6 line wrasse, 1 flame hawk fish.
Do you think it is safe to treat the all tank ? I have no idea how I can catch the goby it is impossible to get him :/

You’ll have to go with prazipro in that case. Three treatments, 8 days apart with a 25% water change before the second and third treatments. Add extra aeration and if you have a skimmer, run it but don’t collect skimmate. Remove any carbon filtration.
