Is this swim bladder?

[Dearmariacountmein]

For the past few days our black moor has sometimes been floating limply at the top of the tank. Other times he’s swimming about and diving deeply. I’m going to try not feeding for another day or two and feeding a pea plus adding some aquarium salt.

But, does it sound like swim bladder if he can still swim freely when he wants? Or is it something else?

For context he is one of 2 goldfish in a planted 94 litre tank with a heater that comes in when too cold. There are also some shrimps and snails and no signs of algae. The other fish is fine.

Sounds like swim bladder. I can't remember if you need to skin the peas before feeding, I think you do. I used a treatment as well, it worked quickly. I hope the fish gets better soon

Mine swam normally sometimes with it as well, but it tires them out & they soon go back to floating.

I don't know if the salt will do any good as I didn't try it, but be careful with the dosage as it can affect snails.

Frozen peas (defrosted of course!) work well. I think I did peel them, I had weather loaches that would play with them like football 😁

Thanks both.

Im going to pick some treatment up tomorrow as well.
