Corn, if you look at the vid with the eggs hatched, you should see the difference in the head shapes. It's hard to explain. The one that's super red, is the female. She's also the only one trying to attack my finger. This pair is about 4 inches. You will also see the females tube hanging down when you get a pair. I really couldn't see any differences besides the head shape. The male with the same head shape was the first to die. I guess that would make sense though. Eliminate the competition (other males) and mate with a female. I still have another female (if my theory is correct) in my 50g incase things go wrong. This was the only other one out of the 5 that survived. Take a look at the vid and let me know what you think. There is no information on these fish at all. I'm going to try to make as many vids as possible. I'll try to shoot and upload on e every 24hrs.
How your fish doing?
