I currently have a 26 gallon moderately planted bowfront tank. I've been on the lookout for a 55 gallon to upgrade to primarily so I can give my Otocinclus and cories proper shoals. I've found a nice tank and stand that I'm thinking about buying, but I'm also on a budget. This tank I'm looking at doesn't come with a cover - no biggie, I can get one for $30 or so. But it also doesn't come with a light. I'm currently running a aquasky RGB+W LED 24-36" light on my 26 gallon tank. So I have two questions about upgrading to the larger aquarium: 1. From a perspective of giving the plants and fish enough light, do you think I could get away with using my current light, provided I figured out a way to extend/secure the brackets on the wider 48" tank? 2. If my current light would not be strong enough for the whole tank, could I use it anyway and just supplement it with a lower cost light (I've seen some White/Blue lights that would fit for around $30)? Thanks!
