Well let's see... He was very vibrant, very active, fins were never scraped, damaged, torn, chewed, he ate very well, he liked having his little cave in the middle to which he would go in and out (never sulking in it). I made sure to never use a net on him, cleaned his bowl and made sure the temperature was the same and to use tap water conditioner.... His water temperature (he DID have a thermometer) was usually 22, usually 23.
Oh yeah I still have his bowl. It's a "goldfish" bowl... and it's bigger than I thought. It's probably 2-2.5 gallons.
So tell me, does it sound like he merely lived not thrived?
