I had to use a large aquarium net the last time I moved the tank- I would guess he is at least 10" long and weighs around 8 ounces.
I really wished I had a small pond in my back yard to keep these fish, but I don't . For now, they are doing OK in the tank. I have a co-worker who has a backyard pond (about 1/2 acre with channel catfish and largemouth bass) who has offered to take these fish in for me, but his grandkids fish that pond. Lease isn't crazy about them ending up on a fishhook, so I guess they will be living here for a while longer....
