8 gallon bowl
Hello everyone, this is my first post here. I am in the planning stages for an 8 gallon planted betta bowl. I will be using a small canister filter and I am trying to decide on a heater. My concern is the fact that the tank is a bowl, so I'm not sure about adhering a standard heater to the side of it. And of course it is small so I don't want to take up too much space. I have considered an in-line heater; I haven't used one before and I'm not sure about using one on a nano. I have a small undergravel heater but I do want to heavily plant so that doesn't seem like the best solution. Anyone have any suggestions for a bowl heater?
