Swim bladder suddenly infected ?!
Parameters: 20 gallon tank nitrates and nitrites ~0 (I use testing strips so Its not 100% but the tank has been cycled for 6 months)
Ph~7
ammonia 0 (api drops) temperature 72
I feed her northfin sinking pellets
She’s the only one in the tank, like 3 inches big!
Filters: a double sided sponge filter for 20 gallons and a new fluval U2 30 gallon filter w carbon in it.
I’m looking for a few opinions from an outside perspective to help my little fishy!!
A few days ago she was swimming tilted so I would skip feeding her for the day and it never got too bad; i did a water change as she was looking sideways tbh but I had to leave and went on a short Mother’s Day trip and when I got back the next day she was totally curled up, swimming by spinning all over the tank, knocking against everything it was really scary. I immediately dosed her with kanaplex and I took out the decorative rocks, some plants, her carbon filter, and eventually her sponge filter as she was getting caught under it. The next day she was amazing and I was so relieved; I scrubbed out the sponge filter and switched the sponges (it was flaking off algae or sand or plastic or something? So I had to be safe) and put the sponge filter back in.
Today she’s back to swimming in circles, but isn’t curled up like beforehand which is a relief. She got caught under the sponge filter again so I took it out.
I don’t know what else to do; if the filter might be making it worse or what to do after the kanaplex dosages if she’s not improving.
Please help!!!! Any advice
I’ve had her for 2 years; she’s a comet goldfish
