Water Changes And Silver Dollars

[dcfeeiv]

so everytime i do a water change in my tank the silver dollars i have(6 of them) they freak out and keep running into things all throughout the tank. and i always feel bad cause they end up hurting themselves
any ideas as to scare them less? would leaving the hose in the tank help any?

i think i would be iclined to leave the hose in the tank for a few hours a day and do things so that they get used to you doing odd things,,,,,have you got good cover in the tank as in plants plastic or real
