I was just wondering out of curiosity what can be the biggest fish you have in a 20 gal tank living in solitude

Personally, I wouldn't keep anything larger then a GBRs or a couple smaller gouramis. I'd say nothing larger then 3-4in and they will be happy. Anything bigger you'd want a tank with more swimming room.

bens right,nothing very big can go in there. i know king bettas get a decent size,you could easily put one of those in there

agree with the previous entries, gouramis are about as big as you'd want to get... dwarf loaches might also work, they're a little larger than your standard small tank schools... but you wouldn't want a dwarf loach in solitude; 5 or more is recommended.

what does a GBR stand for?

Most people disagree but I think a single standard fin angelfish is fine in a 20H if it's by itself.

My uncle has had an angel in a 20g tall for about 6+ years and it looks happy as can be by himself so I think it be ok.
