I had a bunch of fish die while wintering over at a pond store, so the proprietor offered me several fish in compensation.
The first pic of the single fish is a pic of one of the fish that has died and was taken before I sent him off for wintering (i was really fond of this fish and sad to hear the news

)...others that died whiel wintering included a shiro utsuri and a sanke (didnt have pics of these).
The following bin contains four fish. The largest one (the larger of the two shiro utsuri) was already mine and survived the wintering, but has a sore of her mouth (but looks like is healing?).
I would appreciate input on the other three fish, all about 12 inches or so long, all are 1 year old i think. I was offered these find to replace the ones that died. How would you rank the three: sanke, showa and smaller of the two shiro utsuri. If you would like to also discuss in comparison with the larger shiro utsuri, please fell free to do so.
Please be brutally honest...would you recommend to keep or should i donate for auction? I would like to think i have the patience to "finish" these fish, but would I be rewarded or not?
