hello. i have a koi angelfish. i really need help becuase i have noticed it breathing very fast and its gills are somewhat red. they are not completly. it is a closer to a maroon color. the other fish (+ him) have been breathing very fast but none of there gills are red or inflamed. i can't figure out if i have ammonia becuase i only have 1/3 test solution bottles that i NEED. i have been constantly been doing water changes (25% a day) because i recently had a bacterial bloom. my tank re cycled becuase of that.i was wondering if doing water changes would do anything. please ghelp!
they have also been just below the surface NOT GASPING FOR AIR
