My father and I have stumbled into an old friends tank that is an extremely odd shape. We're not sure what we will be doing with it yet as I am moving out soon and graduating college. The tank used to partially arc over a doorway. It was a cichlid tank. He has told us the length, width, and height would normally make it a 600 gallon tank, but with the customization basically picture a stand 600 and about the midpoint of the tank there begins a gradual slope from the bottom, until by the left 1/4 of the tank it flattens out again, the water depth at this point being only about that of a 20 gallon tank. This sounds very strange I know, we will get pics soon, its en route to our cellar in a few days. We bounced some ideas around, and we pondered making it a reef tank with the water level significantly below the top of the tank, at about the point where the slope flattens out, and putting sand on the out of the water portion, down the slope, and on the normal substrate level. Hence, leaving an area of "beach" I guess. Has this ever been done? Could we get some type of wavemaker to get a sort of shoreline effect. What sort of animals could we keep within the same tank on the dryland? We thought of just dryland hermits. This tank is going to sit around for a while before it sees any action. We have started this summer getting into reefing in our own tank and it is going to take a while to get a handle on it. Were just thinking of ideas as we go right now.
