Damsel breathing heavy
I just want to ask, what's wrong with my Damsel? My tank is about 6 weeks old, Damsel is about 4 weeks. He's been doing fine but the past couple of days he is not so active, always on the bottom, breathing hard and when I'm feeding them earlier, he doesn't seem to have an appetite. I went to the check the water and it's fine.
I added about 2 gallons of new water since my water is getting low. Salinity is at 1.025. I'm thinking maybe is the weather... temperature yesterday was about 82F.
