Alot of times small ones wont make it. The experience required, which I mentioned, is about spoting problems early, and treatly delicatly as possible. Any stress and their is a good chance of losing them, Experienced fish keeps know how to avoid stress. Rather newer keepers think it cant be that hard, but these fish are prone to problems and the slightest error very well can lead to death.
Sorry I didnt mean to come off as rude. I wish you the best in your endaveors if you decide to get one.
