thanks everyone it sounds to me well heated and filtered lightly,with Plenty of plants and 50% water changes is best way
thats what i've been doing
i think i will read some of the stickies see if there is anything i can learn from them
I have a veiltail who isn't careful with his fins so he often tears them

so i'm always having to look out for signs of finrot when i think its not healing i put aq salt in, I like to do 50% water changes every 5 days to make sure water is clean, and i use stress coat, i also put oak leaves in but i think the filter, filters all the tannin from them out
i would like to hear from as many people a possible who have had 3 year old bettas
the more the better so keep posting please
