Thank you all for your replies 8D
I'll move them tommorow using The-Wolf's method ^^ sounds quick and easy! i'll let you know how i get on and take some photos too :)
So i've got around 100-150 baby leopard danios in my breeding tank which was homemade by me & has a wool spawning mop & wool grid in the bottom so the adults couldn't get to the babys.
now the danio fry are about 5 days old and the water quality is terrible! the wool has started to disintergrate...
