I'm new, so forgive me if I'm posting in the wrong place..
but I'm getting mixed messages from people on caring for my betta.
Some people are telling me that my new betta won't need a filter..actually, most are saying that.
Is it bad to put a filter in a tank with a betta?
Right now he's in a simple vase, but I want to make an aquarium with rocks, a filter, a plant and a few decorations (for looks, mainly)
I will be looking around the site for more info, but if anyone could clear this up for me I'd appreciate it :)
