I have 3 JDs in my 6ft community tank, 2 of which breed nearly every 3 weeks. They are sharing with (amongst other things) a 30cm gold spot Pleco, so I am not sure if they have been eating the eggs or the Pleco gets to them at night. They have managed to hatch them on one occasion but after they moved them they disappeared. They will be getting a tank of their own shortly so that should fix that problem anyway.
What I am after is info on JDs, specifically spits, EBs etc. What does this mean? And about culling the "ugly" ones from the fry. Tried to find info in the forums but didn't have much luck. I've included a couple of pics of mine, sorry about the quality but they are in the corner of the tank and hard to get at.
