congrats, i have had mine spawn 4 times but they never made it past the wiggler stage. my advice is; leave a small light on for them at night so they can keep guarding their eggs, especially if you have any snails, as those will eat the eggs at night if they have a chance. i tried leaving the light on for the night the second time they spawned, and that was the time they actually hatched. then, they got eaten.
edit; didn't realize there was a second page- cool that you got wigglers, but sorry yours got eaten too... maybe keeping the light on would help at this stage too, though?
