Question: Deep & Narrow Glass Fish Tank..... 4.5 US Gallons
So I've learned alot of stuff from this site, and I know what to do before you set up a tank, and when I get paided next, i'm going out to buy a water testing kit.....
Now I'm thinking of setting up a deep and narrow tank.... most likely freshwater due to my experience level... I was wondering if people knew of any fish in particular that like (or do well) in deep and narrow tanks? Or even long stemmed/ root plants
Thanks in advance

PS; Also, how would I run a filter for it?
