You can remove them with tweezers get you some info.
Don't use the anti crustaceon med by interpet unless you have to its wipes all the benefical bacteria out in the filter.

Anchor worms are most often a problem with newly imported fish and in garden ponds in the summer, and don't often occur in aquariums. Males die after mating and have a short life span, and females are usually seen attached to the fish host. The eggs hatch to produce free-living juvenile parasites, which eventually molt to produce the adult stages. The juvenile stages can live without a host for at least five days. As with other crustacean parasites, organophosphate insecticides are used to eliminate the free living juvenile stages. Adult worms should be manually removed with forceps, and the site treated with a suitable antiseptic. Parasites can be removed weekly, until no more adult worms are found.

You'll have to remove the arowana from the ray tank before you can treat it, there are no ray safe meds that will remove external parasites.
