I was looking in the 40 gallon calvus tank and in one of the large shells were a couple of calvus fry so we decided not to risk the few of them getting eaten so we take out the shell with the babies ad start poring them into a little countainer and a few come out, then we fill the shell up and empty it several times and they just keep coming... long story short the few fry turn into 105 fry... to me this semes like a large ammount of fry for a 3.5 inch fish what are your guys thoughts or is this just a normal batch?
