fish police! help!
hi everyone. i have a 30 gallon planted cycled tank with 10 threadfin rainbowfish, 10 CPD’s, 1 betta, 5 hillstream loaches, one nerite snail & one mystery snail. two of the threadfins are floating at the top of the tank for the last few days & aren’t doing well. one just started swimming vertically & spinning it seems. :/ any tips, advice, or solutions would be insanely appreciated !!
tank temp: 78°
typically kept at 76ish, but there’s a heat wave in my area right now spiking it higher. also note the threadfins have been acting like this a few days ago with no heat wave. i have an air stone running to keep things oxygenated
ph: 7.8???? this seems so high its usually around 6.8-7
is this the culprit? how do i lower?
ammonia: 0
nitrite: 0
nitrate: 5
