Thanks all, I'm not too hopeful for much success seeing as it's just there first time, my sevrum is causing them a bit of bother so he'll probable be shifted to another tank today.
I'm really surprised though, the tank is possible in it's worst condition at the moment as I'm treating for an outbreak of anchor worms.
Any one know hatching times? They must of laid at around 6-30 last night, I'm not even sure how many eggs there were as they were just finishing taking them into there mouths.
