fish behaviour

[rpkerr]

hello all,

I have a 2 month old tank fully cycled ph 8.3 nitrite 0 ammonia 0 nitrate 15ppm. I put in 1 fish a blue damsel has been perfect for 2 weeks until I did a water change. now the next day the damsel is not active and is hiding. is this normal. tank is a 30 gallon tank with cured live rock.

How is the salinity? If this happened after the water change, I'd want to look at the water change as to what could have occurred.

yes that water change caused the salinity to go fro 1.025 to 1.028 just di another water change to bring it down hopfully that is the fix
