I've had my 10 gallon tank for a while. It's doing okay, but it is kind of an eyesore. I got it for free from somebody. It's just a cheap tank with a waterfall type of filter and some rocks in the bottom. One of the bulb sockets is broken. I have three brilliant rasboras in there. For Christmas, my wife wants to get me one of those glow-in-the-dark setups with glow-in-the-dark fish because it is the top seller on Amazon. I'm not sold. I think glow-in-the-dark fish are unnatural and belong next to a lava lamp in some college dorm. I would like to upgrade my tank. I think I might like a different type of filter. I think I remember seeing something that can go on the bottom under the gravel that is supposed to be good? I dunno. Does that make sense? What else should I be looking for?
