I have a 10 gal planted tank and everything looks nice except ugly cheapo hood. I would like to get something decent for both look and plants. I am thinking about getting 24" nova extreme T5 for freshwater, but would it be looking funny since it is 4" inch longer than the tank? I don't understand why these companies discontinued smaller 18", 20" fixtures. I am open to any suggestion/recommendations. Thanks a lot for your help.
