I am new to this website and somewhat new to fish keeping compared to some of you (only 3 years) i have a 45 gallon tank which has 4 fairly large angels (boddies between 4 and 5 inches with long fins) i also recently added a pleco. The tank has gravel and plastic plants but no live ones, and is filitered by a fluval 304. I was wondering what you guys think about this tank and anything i could add/change?
