Best method to remove them? I've counted about 20 of them.

You can try to pick them off with tweezers and give the glass a wipe with a sponge.
Also give the aquarium a good clean including the substrate and water change.
Cut back on the feeding.
There are some fish that will gladly eat hydra such as blue gourami (Trichopodus trichopterus) and molly.

They have likely entered the aquarium as hitch-hikers, either on plants or in fish bag water.

All the best

Yes - it was NT Labs 'Anti-Fluke & Wormer' at half-dose.

Active ingredient is flubendazole. Raw flubedazole (as in dog-wormer tablets etc.) is a devil to dissolve for use in aquatics, but it's already dissolved in the NT Labs preparation.

I've used it two or three times to get rid of Hydra and at half-dose it didn't kill my snails or blackworms (though the latter seemed somewhat concerned for a while!). I mean to test it at quarter-dose if/when the opportunity arises.

Incidentally my Hydra were the green variety - yours are the brown ones (i.e. they don't contain symbiotic green algae) but I can't see a reason why there'd be a difference in response to flubendazole.

Someone, somewhere at some point was looking for (I think) brown Hydra ; I can't remember if it was on this forum or in Another Place.
