i have a one gallon and im thinking of getting a small heater.
im new to fish owning, so i kinda dont understand how to tell the certian ammount of watts to tank size ratio
im not looking to go expensive, im short on cash (my previous fish was sick that emptied my pockets haha)
ive been to petco and i've seen a "betta heater" for 2 gal and up, i cant remember the wattage
what do you suggest
oh and forgive me for asking;
do bettas need a little light at night, i have mine in a room with natural light, i wasnt sure if i should get a tank light or not. i guessed since they are an animal that they should get some sleep. but thats my unprofessional opinion hahaha
