If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress.
Does water change stress out fish?
The benefits of water changes must be balanced by the stress caused by a sudden change of your tanks water chemistry. If tank water has similar pH, GH and KH as tap water, changing 50% (or more) of the water at one time will not affect fish.
Can I do a complete water change in my fish tank?
Its best to keep your fish in the fish tank when you clean. Completely replacing the water in the fish tank is a bad idea because it will remove beneficial bacteria that live in the tank and reset the nitrogen cycle, which could kill your fish.
Do fish like water changes?
Discus and other sensitive fish species thrive well under very low nitrate levels, and thus need frequent water changes, but with only a small percentage of water changed each time.
Why are my fish hiding at the bottom of the tank?
To protect themselves, fish will instinctively hide when they are uncertain, frightened, stressed or uncomfortable. Even long-time residents may hide when a new fish is introduced until they are all comfortable with their personal territories. Within a few days, the fish should feel more secure with each other.

How often should you add water conditioner to your fish tank?
You should do a 25% water change every two to four weeks. There is no reason to remove the fish during the water change. Make sure you stir the gravel or use a gravel cleaner during the water change. When adding water back in to the aquarium, use Tetra AquaSafe® to remove the chlorine and chloramine.
