If your looking to breed pigeon blood, you could have a spot of trouble.
The colour form 'pigeon blood' came around through extensive breeding projects. There is little wild blood in the strain anymore and with each generation that is born and raised, natrual instincts are slowly forgotten. This has affected the fishes ability to properly raise its young. Although some fish still do a great job and rearing their fry many of them have simply lost their parental instincts and eat the young before they bcome free swimming. This is a problem becuase as you probably know, the fry eat the layer of mucus the parents secrete during the breeding process. There are a few alternative food that could be used if your able to find them in stores but many fry die becuase they're taken away from their parents and cannot find any food which is offered to them.
