The tank conditions are within normal parameters. But only by using the type of ammoniakit that tests for free ammonia not total ammonia. Ph, nitrite, nitrate, are all normal too. I did a big change this morning. She can hold herself vertical now but still with her head at a bit of an angle upwards. When I was changing the water, she was diving down to the lower level of the tank. But when I was out of there, she resumed at the top. But again more at a 45 degree angle. So she improved with extra air pump stones and 60% water change. The water has been ok. It seems the more I look it up, it’s saying 1) either she’s not getting enough oxygen and all the tests are wrong, or 2) a buoyancy problem. I’ve tried peas in the past cause she looked bloated for a while but it passed. I put the half teaspoon per gallon of salt, water temperature 72. I wish this wasn’t happening.
