gobies breeding

[aydin]

hi to everyone i have a pair of diamond sleeper gobies or orange spot i got them a month ago and are the best fish i got they are 10 times better then my golden head sleepers they dont stop working thanks to them my sand is spotless. Anyway my question is that they have breed its started with one fish burying the other and then they both disappear into there cave 3 days ago i noticed small fish swimming around in another cave they dug next to where they sleep i put some food in there marinara mix which i put through the blender but the worms eat it all any ideas if they will survive thanks
