I have had two different batches of babies in the last 4 months. I had one male hold the eggs in for a month so I wouldn't get too worried just yet. I have had small amount of fry so far have been 5 last time and 4 just yesterday. One thing i noticed is that only the stronger more alert ones survive, Ive had some that have stayed very small and they ended up passing. I don't think it was competition for the food because i feed thousands of fresh brine everyday twice a day, I mean the tank looks like a snow globe. I just think that some are born weak, i had two survive my first batch of fry and they are the two that grew the fastest. Just make sure to have lots of brine in hand.
