I started with 150 eggs. I lost about 30 eggs due to fungus. The rest did hatch but at free swimming stage I already noticed some had trouble swimming. I suspect these are the ones that never developed a proper swim bladder. Today I did some culling and removed about 20 belly sliders. I can see why these are still rare in the hobby. I don't know if the air bladder issue will develop with the normal ones but I want to start with all perfect ones to see if any will develop the issue later. As for now I still have about 80 healthy fry.

That's really odd. I hatched and raised this first batch in a very low water level already, 7". I can't imagine water level in the wild being lower than this. I'm going to soften the water even more this time and see what happens. They just laid again today.

I managed to save about 100 fry but 10% are belly sliders. I wonder what's causing this to happen.

i use a reusable coffee filter and just float it in the same tank

Anyone here raised fry from this fish?
