Can anyone recommend a light fixture for a 20L tank (30X12X12)? I just bought a 20L tank to house my 1 month old baby silver angels and don't have a light fixture yet. I currently have a coralife 36" for my 38 gal, and I don't have any problem with it, and so far I have looked at both Coralife, Nova Extreme, and Odyssea (bad reviews on ballast). There aren't many options for a 30" light fixture. Thanks.
