i had a group of 10 babies. let them grow in a 2ft tank. i noticed one was getting coloured. so i trook him out aswell as 3 supposed females. i put them in a heavily stocked 4ft tank. within 3 days one of the females was holding (about 2 inches long for mum and dad) nd to my surprise she is still holding and im about to strip her now. so much for them not keeping there first batch. yay
