ok so I've had a guppy that seemed to be doing alright but this morning i saw him/her wrapped around the filter intake i assumed he/she was dead but when i turned the filter off to remove him/her they swam off a little shakily and they aren't swimming that well so i sectioned him/her off from everyone else and am now trying to deside what to do about him/her what are your oppinions if it is to euthenise what would be my best method for the easyest most pain free method?
