Ya. Newly bought fishes were from a brownish color water tank in shop.
Before introducing to my tank, 1/3 water mix and then 2/3 water mix in an hour interval respectively.
New water change of 60% was over night tap water
My guess is the new fishes itself ain't healthy in the first place
Btw do u guys test your water quality regularly?
their browish water is it black water? meaning with lower ph water

if u wanna be v safe, quarantine for 2 weeks

then after 2 weeks, use drip method over 1 hr to acclimatise your new fish to the fish tank

Also to use water test kit to check out ph value, temperature, ammonia, nitrite and nirate regularly

if u want, can further test carbonate and total hardness
