Will first need to confirm. Pics under white lighting will be very helpful
If hydroids, they are no harm to the ponies however are a nuisance and should be eradicated. What is safe and works is the use of fenbendazole (FBZ) for a few days.

Rare, but can happen. They aren’t parasites, they are epiphytic, they live on the seahorse’s skin. They do cause irritation.
One possible solution is chloroquine at 12ppm. That will kill these. Seahorses should be ok at that dose.

The seahorses are in my lab, we pump seawater for all of our systems.
So it probably came from the water.
Chloroquine wont work since we use seawater

Have you reached out to other breeders? I know Alyssa at Seahorse Savvy was very helpful when I had pony issues a few years ago.

@Jay Hemdal , what about formalin?

That's the same as the Kuda, correct?

From what I can find about eliminating hydroids "IN" a seahorse tank, Fenbendazole and formalin can be used. However, I can't find much information about hydroids actually attached to a seahorse. Most of the literature discusses hydroids and dwarf seahorses.

Here is one place I found treatment recommendations.

Learn more about Hydroids. This article will go over how to prevent and eliminate these unwanted harmful pests in Dwarf seahorse and seahorse fry systems.

This is an interesting article about hydroids on a seahorse in the wild, but doesn't give much advice.

And here is another breeder's treatment advice for using formalin - it doesn't discuss hydroids specifically, but might give you an idea of what a formalin bath/treatment should look like. (Done properly, seahorses tolerate formalin well.)

Hope this helps.

@Jay Hemdal , what about formalin?

No, not in a flow through system, just like with chloroquine, the hydroids will just return with the incoming seawater. I suppose the issue could be managed with either formalin or chloroquine baths every few weeks or so, but it will keep returning.
