I was wondering if the runts of the spawn still grow up to normal betta adults?
thank yooh!!Surprize30: sorry I know your question is to curlyfatbottom, but I'm just gonna stick my thoughts in, with betta's yes you could do that, the fish may act slighly depressed for a couple of days, but you could hang the fish in a breeding trap in the tank so it could still see its siblings. Also if you wanted to keep a paticular fish for further breeding you could seperate that/those fish to make sure they suffer no fin damage, or illness if (god forbid) it got into the fry tank, basically if you wanted to booth the growth, and keep the fish completely healthy you could do this, but not with fish like platies or guppies, as this would make them unhappy.
When I seperate my Bettas, I give them an anti-depressant. It really helps!!Or float them in a clear cup.
U can fit more n control the amount you feed
U can always introduce the sibling back to the tank
But y put them back
Since you took the time to care for it by itself
If I'm going to single out a fish
I won't put it back in the tank
