If I had not had a tank crash due to disease back in 2005, where I lost fish I had already had for 3-7 years, I think I still would have:
emperor angel
mimic tang
harlequin tusk
tomato clownfish
royal gramma
I have lost some fish to surfing, some to other fish eating them, some within the first month (probably not healthy to start). But the biggest cause of fish loss, for me, has been disease, which is why no matter how much of a pain it is, QT and having good meds on hand is really important.
