What do folks see at the main difference when younger b/w male and female chancho? I thought I had a male, but Ken Davis was at my house and he thought the below fish was likely a female (note, the pic is 6 months old - will get an updated pic shortly). I have heard black in the fin, which this fish does not have at all. But I have seen pics on the web of supposed females w/ and w/out black in the dorsal. The below fish came from COTA. Unfortunately it is in a tank where capture is next to impossible, so venting is not possible at this time. Thanks.
