i have a 10L bowl (2.5gallon)
with my betta in it (percival), one aqua one 25W heater and an aqua one 300f-LV filter, i have the spray bar pointed straight up to minimize current in the bowl.
seems to enjoy it becuase he is swimming around a fair bit more than before although not sure if this is just becuase he is fighting a current. he also enjoys sitting on top of the filter and heater.. he also seems to sit right at the top on the very edge of the bowl, before i had the filter he sometimes went down and sat in his cave. thoughts?
one other question is i acidentally left heater on when i did a water change, how likely is this to break the heater, i didnt notice anything different about it but i dont have a themometer to check.. i have not seen the red light flash yet but i dont know if thats cos its at the right temperature. thoughts?
