Why is my wolf fish upside down and struggling? Swim bladder?

Updated On September 23rd, 2025

Pet's info: Fish | Freshwater Fish

I have a wolf fish that seems to be sick. He is upside down in the tank now for 24 hrs. He is still breathing but seems to bee struggling. I have increased the temp in the tank and added aquarium salt. I have added a bacterial and fungal treatment today into the tank. I have used some moss to prop him up correctly in hopes this will help him. What would u suggest? Please help.

Thanks for reaching out about Wolfy. Floating upside down is a serious concern, possibly involving the swim bladder or intestinal tract. Typically additives to the water are not absorbed systemically but the salt might help decrease osmotic imbalances in the body. A radiograph could help determine if fluid is filling the swim bladder, and then systemic antibiotics could be administered, probably vi injections. Good luck.
