It's set up, cycled (been up and running for at least a month now), and currently has one betta and two ADFs in it. I was just wondering if and how I would be able to get away with adding some sort of algae eater(s) and/or some other small fish. I'm not determined to overwhelm my tank with too many fish or anything (I have a 40 gallon being cycled right now), but I'd really like to liven it up a little if possible. If not, I'm perfectly happy with what I have in there. ^^ Any suggestions?
