Well, I'm thinking about getting a few Garden Eels. The tank is going to be a 28 gallon high Marine PLANTED tank(diff kinds of algae and such), dimensions are: 24 inches long, 20 inches high, and 12.5 inches wide. The sand bed is going to be 6-7 inches deep. I know that they need very good water quality, but that wont be a problem at all because the tank is going to be full of diff algae and such. What are your thoughts? Got any info?
