I have just bought a 50 gal tank with 4 chilids 1 silver dollar 1 yo yo loach and a pleco not sure what kind the guy is sick and cant look after them anymore. Iam going to take as much water from the tank with me as I can and move the fish in small garbage cans plastic with locking lids. My question is how do I eventually get them use to my water should I do a 25% water change each week adding my water these fish are about 3 years old so I dont want to stress them too much.Thanks Pat
