I have had an arc-eyed hawk for 2 years now and I have finally become sick and tired of him ruling the tank and driving my clown, damsel and dottyback into seclusion. He will eat anything large enough for his mouth so I am thinking of buying some fishhooks and line and hooking him then trading him in at the shop. I need to know what size hook to use for this size fish that would work and any other tips from others who have used this method.
