Originally I was going to post to find out how big a JD had to be before they could spawn. I was going to ask because they had been acting strange lately, like acting aggressive towards the Pleco, which I had never seen them do before. Well that question was answered earlier today when I was able to find eggs inside the structure I have in the middle of the aquarium. The thing is, is that when I got home from work tonight and looked inside, the eggs were gone. I can't see anything in there now. Would they have eaten them? Just curious to see if anyone has any input on this.
