New here, Have kept betta's for about 35 years now, i currently have 6, All bar one and in 54L tanks, my prize possesion is a Halfmoon mustard gas male who has a whole 180L tank to himself.
I dont agree with betta's being kept in anything thatisnt
a tank over 30 Litres and does not have a filter/heater.
My oldest betta is a royal blue VT male who is fastly approaching his 8th birthday - Proof that if you look after, and treat this fish with respect and understanding, they can live alot longer than the average age expectancy of 2-3 years. i'm also from the UK so i guess my views will differ from many users on here, again you'll just have to get over that, as we are all here for the happy life of our betta's arent we? :)
