Catch a sick fish?

[renouart]

I started this question on New to Hobby, but just wondering if some other ideas show up here. I catching them while eating, and flakes on the top. I plan to try first thing in the AM, while they are asleep. Any other thoughts? I am running out of hope of getting them out of the tank!

Depending on the size of your fish, you can try using a fish trap and using food as bait to catch your fish.
