so i have bought a betta today and the container m sister supplied me with is a 2 gallon glass cookie jar (because an actual tank cost more than can afford and would also be difficult to clean out ) also this is my 3rd betta now 1st one died because wouldnt eat 2nd one died yesterday due to taking the advice of fish owner and putting a heater in the jar ... Raindrop got cooked T_T and 3rd one liks to float to the surface on its side and stop moving untill poke it at which point it swims all over place
