More news about the fry. I found like 6 fry that could not swim down it was really sad they were stuck at the top. I took a video.
But good news I am floating them in a cup in the tank. I was afraid that maybe their swim bladder was not developing right and I would have to cull. But I made up a gallon of Epsom salt water. I added it to their cup and most of them are all better and it's only been a few hours since I did that. Woohoo !
I will have to show a before and after video of the fry with the problem.
What other stuff can I start to feed them?
