Yeah only one egg. When I researched to find out which of the species it was from I read that the female pygmy only lays one egg per male and since I only have two of them I was assuming that was why I had the single egg. I have an otto, CPD, micro rasbora, and lamp eye killis in with it. Do you think any of them will eat it? I would do the jar idea but the tank is kind of small to take up too much room with a jar
