Hello one and all.im hoping that one of you clever folk might b able to help me identify this fish.my guess was a grass carp/koi hybrid? I know the pictures are far from brilliant but this fish does have barbbles so I built the pond in my garden just over 3 years ago.2 years ago my koi spawned. And as a result I have 2 koi of two years old.now 2 weeks ago I noticed this odd looking thing the same size as the other 2 young koi.but behaves very differently.so after the last 2 weeks of giving me the swim around I managed to catch it yesterday and take some poor pictures until it jumped out the net and back into the pond.the current residents of the pond are several koi, 2 albino grass carp, 1 black grass carp, 2 sturgeon, 4 golden tench and 2 golden orf. Any idea what this might be? Many thanks in advance. Hazey
