Hey Everybody, I just bought an Amazon Sword for my Goldfish Tank and realized after the fact that my light was not bright enough. I was wondering if it's possible to keep an amazon sword in a 29 gallon tank with a 20 watt plant bulb. I've been trying to find some 24 inch bulbs at 60 or 90 watts for my tank hood but I can't find them in Petsmart or online. All I can find in the 24 inch range maxes out at 20 watts. As of right now I do weekly water changes and fertilize it every time it gets changed. If anybody can give me any suggestions on any of this it would be appreciated. Thanks
