I have a Synodontis Eupterus that i have had over 18 years and once had a common plec for over 20 and unlike now that one started in the typical 30 inch tank.I've never kept a fish over 15 years, so yes that's pretty good for captive fish.
I had a couple tin foil barbs for a short time back in 1977, when I knew nothing about them.
But they grew just as fast, and I had them in a 10g LOL
I don't recall what happened to those fish. I got them just before my first child was born and we moved to the country.
But I do remember also having a bala shark and a pictus in that tank and probably a betta.
Most probably perished in the move.
