Oh Man, what is it with you and all your fish spawning :facepalm: :slfg:
I personally would have moved dad aswell, they take wonderful care of their eggs, can you pop him in the tank that you now have the eggs in??
I bought a breeding trio (complete with eggs) of ya normal BN's, about a month ago, (not sure if yours are normal :slfg: ) pic on google of yours looks very similar to mine, a common bristlenose, the eggs where just at wriggler stage, made a breeding tank out of a oversized lunchbox with holes in the bottom and sides etc, floated it in the tank along with dad his cave and the bubs.
Came home the other day to find dad had gone into the smaller hole in his cave and clearly couldn't get back out :facepalm: so he is now DEAD :an!gry
I do have another male lined up so will see if he has what it takes for the girls to be attracted to him
I have just released the fry into a smaller tank, amasing how fast they grow.
Good Luck with yours :happy2:
