I haven't heard of too many white eye kamfa being fertile but I have seen it. Even red eye with those are still rare. Super red dragon and gold base you have better chances of them being fertile but it's still not a guarantee. My super red dragon's just spawned a few weeks back and I have maybe 10 free swimmers in the tank if that. He's my first one of those I've had prove himself fertile. This is all on this side of the pond though. In Asia they are years ahead of us in the game and probably have farms of white eye fertile males...lol. Most of what we see over here are their throw aways. They already have the original secret recipe we're all trying to figure out over here.
