So I ended up with some betta fry. I read that they need to start eating once they start free swimming. At the moment most of them still have yolk sacks some don’t. They dont seem to be able to swim for more then a few seconds before sinking to the bottom till the dad picks them. Current problem is that I wasn’t expecting babies so I don’t have any food. I ordered some micro worms but they won’t be here till the 19th. Is there anything else they can eat? And is it time to start feeding them?
