Blue damsel...How to fish him out?

[Brent F]

I recently caught a pair of damsels that way. I turned off the pumps and used a feed ring (a plastic ring that floats and keeps food from spreading acrooss the surface of the tank) to keep the food in the front corner. They had no choice but to come to the front corner of the tank. I had the net waiting below the ring. They swam above the net one after the other.

The difficulty may be keeping the other fish out of the way
