Can anyone tell me the sex of this JD? Reason I'm asking is because I have three of them all in the same tank and this is the bigger one out of all three. Its a very active fish and I noticed when it was eating tonight it looked like its belly was big. I don't know if this is normal for this species or could it have eggs in it if its a female? It seems to be swimming around fine but I did notice it in a cave more then normal today.
