My african pikes kinda just go play in the other corner and come back over when im done, the only fish i have that gets slightly stressed is my peacock bass
I also have piranha but for the love of all that is holy they acted like I was about to torture and murder them during a water change. No matter how calmly I moved around during the water change they would go nuts. One even looked like it "passed out" or "played dead" from the level of anxiety.Zander_The_RBP;4109554; said:i voted 2
my piranhas act like frightened children when i do a water change (dashing all over the tank if the hose comes near them, staying on the other end of the tank etc) but they react the same way even to when i just put my hand in the tank so.....
anyway they always seem to really enjoy the fresh water after a water change.
10 is DEATH!Egon;4114478; said:I voted 10 because I have a drip system. I think a gradual water change over 24 hours is the best and lowest stress possible for the fish. Any type of disturbance to the tank causes stress. Water changes are at the top of that list.
