This is the first i've heard of ghost knives spawning in captivity. Very interesting to see if you actually manage to get some of the eggs to hatch. Please, pictures if you do!
Easy to sex, females have pot belly underneath their chin, male doesn't.
this is noticeable around 14cm+. Like others have said males look like a horse face while females look like a puppy face. if you look at my pics, the blackk one is the male.
if all goes good. i'll be doing a full journal with pics.
when i have spare time, i will post my project so others can have fun too.
share the knowledge, ive done countless of experiments with ghost knifes, i know their secrets and behaviours and most importantly to be able to keep multiples in 1 tank).
anyway if this goes well, next project will be an elephant nose
