I think you may be dealing with a spinal issue that some captive bred polypterus have. I have a senegal that has the same issue. It started out with him swimming odd, then progressed to him swimming violently and erratically out of control which was really hard to watch, then got a lot better. Now you can see that his tail doesn't move normally, but he's gotten used to it and actually lives pretty normally. It really sounds like what you have.
I would recommend keeping an eye on it and making sure he continues eating. If he does, then he'll probably be ok living with it. I have heard from a few people that it just get's better eventually sometimes. Here's the thread I made when it happened to mine.

Hope this helps
Try to avoid feeding during epsom salt treatment.
Epsom salt use 1 tbsp. Per 5-10gallons, Do it for 3 days.

Oh wow thank you everyone for chiming in! It means worlds to me!
To answer your question directly, it could quite possibly be a spinal issue! however, this would be the first time it has come to light or it's a brand new issue.
Rou is my first bichir so these symptoms and behaviors have been relatively new to me other than from research and reading. He looked/acted healthy since the day I got him up until the point roughly two weeks ago when I noticed he wasn't using his tail. It seemed sudden, or perhaps I oversaw it until it got to this point but even then it wouldn't have been overlooked too long. He has always been relatively lazy and more active at night so acriveness wise he appears the same.
I'll definitely keep an eye on him and update everyone if there are any changes. I'll also go ahead and add some aquarium salt, as someone recommended, during tomorrow's water change to see if it helps any and if not it won't hurt anyways!
I'm just super attached the the guy and I'd hate to see him struggle/suffer if I knew there was something I can do about it. But for now he doesn't seem to be in any discomfort, he can still swim to the top on the tank and back down which is good. Just hope it doesn't get any worse!
Thanks again everyone so much for the tips and advice thus far! I should of made an account here ages ago haha.
Yeah mine happened really suddenly. One day totally fine and the next day convulsing around the tank. It seemed odd that it started suddenly but i guess that's the way it can happen as they grow.

Welcome to the poly section.Sounds like a plan! I was planning on doing the water change earlier in the day anyways since he gets fed during the evening so there should be a good size buffer time between then!
Thank you very much! I'm glad to finally be here![]()
So I little update, I treated the tank with epsom salt (not aquarium salt as I didn't realize how different they were, my apologies!) and, for a little while, he seemed to be doing better and was even starting to use his tail to swim!
Today however he to have took a turn for the worst and seems to be struggling even more!! He is starting to float up tail first and spends most of the day "parking" himself under plants so he can sit still. Otherwise he's gradually floating upwards. Could it be what he is eating? I try to give him a diversity of foods, but his main diet consists of Hikari brand sinking carnivore pellets. Should I switch to something else? Or is something else the matter?
He is still eating normally, and other than this issue he seems rather healthy. I'm just not sure what my next step should be with treatment. Thank you so much in advanced!
