Lernaea (Anchor Worm)

Anchor worms are parasitic, totally free swimming crustaceans that attach themselves to fish and feed on their blood.

The treatment consists of removing the fish, and touching the anchor worms with a camel hair pencil brush dipped in paraffin oil, or turpentine, and then removing the offender with a little pair of tweezers.

0.1 per cent answer of potassium permanganate could be utilized instead of paraffin oil.
