So... I keep fish...but they are in confined spaced tanks...this tank was with my first non veil tail betta... He was Johnathan, a halfmoon betta... He did so well for many months until he died last year... The tank was 0.7 gallons.. But bettas prefer 5 or more gallons.. And never felt guilty when I got Johnathan until now... I never put a betta in here... But I had a single royal tetra (requires 20+gallons).. 2 boesemani rainbowfish (30-50 gallons..) and a kuhli loach (10 gallons but 20 is the most recommended)...i did bought a 2 gallon tank but my entire family even my Lil bro rejected it... And ever since that... I think I might get depressed soon..I just want to make my fish stress free...and after all, my home is semi small and there's lots of things in there.. Is my family correct or I'm correct.. I need answers..

What.
