Ever truly notice the tiny unique differences you may see in stripped cons. Some may seem to to carry more color in the body or fins, some may have bluer or darker eyes,some may have a stronger presence in the color contrast in the stripes and have different body shapes.
I have recently read up on people who have collected cons down south out of the rivers and people have noticed unique genetic traits within species collected in specific areas. It seems over the years certain traits pop out to be dominate or co-recesive for that matter in a community of fish basically making species in area more unique than their neighboring species.
A problem for the the fish keeper when getting fish locally is there are many factors that can be against you that you may want to consider when picking out a convict. Stripped convicts body color will vary heavily upon their surroundings. In a darker tank the skin tone can become darker and the stripes will become more present. When in a lighter colored tank cons can sometimes almost loose their stripes and skin tone becomes lighter. The fish could also be very inbred, there are a few things to look for with this. When fish are continuously bred brother sister and there are no new genes adding into the mix you will notice the fins will droop and in one article I had read visually in the forehead of the fish there will be an elongating effect from the result of accesive inbreeding.I did read one article that would challenge this where someone stated online they knew someone that had breed the same specific line of convict for 30 years….Its hard to believe. Another thing to consider which has really occurred since the dawn of the flowerhorn fish is hybrids. Fish in the stores may be labeled “convict” but they maybe tainted or mix with other fish. A good example is the blue convict found on the market which is possibly a cross of a convict and a honduras red point (possibly).
There is no right or wrong fish to pick , if theres something you find interesting or unique I recommend you grab it if its a con since there usually an inexpensive fish. Below are a mix of stripped con pictures, some are mine some from the internet just to help show stripe con variations. I also picked grown up males as the examples. There are far more color variations in females and for males their difference show up more in fins,eyes, body shape and body coloration.
