Currently feeding my by Betta fry on BBS, they are now 3 weeks old. What else could i feed them on? How long are they supposed to be on BBS for? How big should they be by now?
Here's the results of that guy's spawn, with pictures and sizing, from egg to about 11 weeks old.
You can try introducing daphnia. They should be big enough for it by now. It comes frozen in cubes, and is quite convenient. My fry in the past have always loved it.
