It's amazing how many fry they can produce in a short time. I have since stocked BG and Res . My supplier told me they were between one and three inches when I got there to pick them up I found that the size was probably one and a quarter inch max they are so small that I can't get them to take fish food yet even if I grind it up to my it smaller. So hopefully with lots of Fhm fry being produced they will have plenty to eat
