Hello, I have a 10 gal. tank with two small goldfish about 2 inches each, 2 dwarf gouramis about ½ an inch each, 2 African Dwarf Frogs and a Kuli Loach. My parameters are approx. 0-20 nitrate, 0 nitrite, 0 chlorine, 150 GH ppm hardness, 120-180 KH ppm alkalinity, and a very consistent 7.6 pH. I recently noticed that my Kuli Loach was swimming very wobbly and aimlessly with little control. At first it seemed to be a swim bladder infection but then I noticed red markings on his pectoral fins and assumed it to be an ammonia spike. I did a 50% water change and chemically treated for ammonia. He still appears weak with no appetite and is just wobbling around the tank. Sometime the loach will float at the top and other time at the bottom, but not for long periods of time. He does this with the light on which is an unusual characteristic for him and he also has little to no reaction response. I am not sure what to do, any answers?
