This hobby is very unforgiving, I've lost a lot more fish/corals/shrimp than I've been able to keep alive the last 10 years. For me the only way this is ok is to learn from mistakes and not make the same ones twice. I keep a massive spreadsheet with all my stock of the last 3 years and reason if they died. Unfortunately livestock still dies despite our best efforts. Lost my moorish idol over the weekend that I had for over 2 years, sometimes it happens for no apparent reason.
Most pet shops employ temp guys over weekends to help, and they aren't always 100% clued up, so best is to research everything properly before buying anything and take some advice from the lfs with a pinch of salt.
I speak from experience, a I worked part time at VIP Pets in Cresta for 10 years from the age of 16 (1999-2008) and it is impossible to know everything, especially when I just started as a high school student. Nowadays I am on my phone constantly on Google when I'm in an lfs if I don't know the specific species or its requirements.
