Hey Saltcreepette, how are you? Wait till around the 5th spawn or so before attempting to capture and raise them. Its not likely to work out with the first few spawns cause they don't start out as very good parents normally. You can make records now and record the spawn date, hatch date and numbers the make it to hatch approximately. By the 4th spawn you should be able to predict the % of infertile eggs, the hatch night (probably the 7th to 9th night) after they are laid and the successful hatch percent. And if you really intend to raise them, get the tanks and equipment ready now and start practicing keeping all the cultures alive for more than a couple days. Get all the air stones running and have your battery backups operating. You have to be able to sustain the cultures and hatch brine with reliablilty like clock work every time, even if the lights go out. The time to do all this is not the night of the hatch.
