I am about to upgrade my betta's tank (yay!), from her tiny filtered 2.5 gallon, to either a 5 or 10 gallon, anyway, I have a few random questions that I am going to try pack into one thread
I am going to use an aquaclear 20 to filter the new tank, but since the current tank is currently very under filtered and since I can't upgrade for a few months (I am travelling for the summer, so I am setting it up once I get back to my normal house in a month or so) so I was thinking about purchasing the filter a little early so that the current tank can have a decent filtration system, is it ridiculous to have an aquaclear 20 on a 2.5 gallon tank? I've heard of it being done successfully and my betta is a very strong swimmer for a betta.
Is it 100% necessary to have a lid, I was thinking about getting some mesh and covering the top of the tank like that to keep my betta from jumping out, can anyone think of a reason why this wouldn't be a viable hood?
If I don't have an actual hood, I probably can't do any aquarium lights on the hood, do betta fish actually need light, or is it just so us humans can see the fish?
