Hey everyone, its been awhile since I have posted but I was looking for some opinions. I found an interesting tank made by Mr. Aqua, it's a 12 Gallon Long tank (Dimensions 35.4 x 8.3 x 9.4 Inch). It is a rimless tank so I would have to fashion some kind of seal for the top. Just wondering if this would be suitable for O. Mercatoris? Also the sump would be a 15 Gallon tank with skimmer and other filtration. So we're talking about 20 gallons of water in a small tank. Your thoughts would be much appreciated, Thanks!
