When I first got started I had a 10 gallon with some guppies and a couple mollies. Damn if one of the mollies didn't try to kill all the guppies. No more mollies.
I have a dwarf puffer that got along well with the otto he shared his tank with for months. Then I was doing a routine water change and couldn't find the otto. He is just gone. I am sure the puffer just ate him one day. But, the puffer is cute. He now has his own tank.
The last bad purchase was letting my daughter talk me into Princess the fancy goldfish. UGH. I put her in the 60 with the community fish until I could get her own tank set up. All that for 1 goldfish....
