Fish doing Backflips

Hey, everyone I've been trying the Walstad method for a year now almost, but I feel as though right when things are going better something goes wrong. The plants are doing well finally and growing with new growth. Ammonia is 0 mostly due to plant growth, pH 7.4, temp 74, 10-gallon. I've had Corydora habrosus the whole time I've been doing this type of tank. I got 6 at the very beginning and over time only two have stuck around to today. I even got another 4 at some point 3 months ago to try and bring the school back up. All 4 new ones have died but these two fish have been resilient and stuck around. I also have cherry shrimp, ramshorn, and MTS that are all doing fine and breeding like crazy.

Now I'm worried because one of Cories are literally doing backflips. I'm thinking that it's due to constipation, as it seems most of my fish that have died seem to have died from a fish bladder issue. Seems like half my fish die within a few weeks when I get them and then if not then a few months later due to a swim bladder issue. I don't know what I'm doing wrong, I keep thinking it's because the fish are sifting the sand and eating stuff they shouldn't or maybe its the food. I don't know what to do any help would be amazing I just don't want to lose any more fish.

Did your flow get turned off, or just down? If down and your water cleared up, then I'd go with that flow setting.
It wasn't off but it was barely on. It is at around 3/4 blast and got turned down to 1/4 blast on my 95gph pump, so it was very low flow.
I'd leave it at the 1/4 setting. You don't really need a lot of flow anyway for such a small tank.
