so one of my favorite bettas that i got over a year ago from a table decoration at a formal dinner died this morning
. i saw late last night that he wasn't super perky like usual and then i noticed his scales were sticking out. i tried to make him as comfortable as possible, and when i woke up this morning, he was dead in his little pineapple house..
but i was wondering how does one "sterilize" a tank after a fish got sick from something like dropsy? i don't want my next betta to get the same disease. i saw some people say just to rinse the tank and plants with hot water, leave tap water so the chlorine can help, and some other small things, but any suggestions?
the tank is a 5gal tank
