Well the plan is for it to be my fishes happy ever after tank. It would be more than double the water volume for my fancy goldfish and plecs. With this sort of sized tank I would probably get a couple of onion plants in some sort of vase, some more fancy's and another plec, specifically a royal panque. I know strange combo. I'm tempted to get an onion plant for their current 200L but I'm not sure if the tanks to small. I can't find the link but crinum thaianum, I've seen a picture of some guy holding the plant out of the tank and above his head, so it was something like 6-7 foot, but that was a high tech tank that I seem to remember it being in. The thing is, if me and you do buy this tank/cabinet, we still need to buy filter/heater/lighting so that mounts up. I've only really put thought into the filtration and it will be one of the high end fluval fx externals. It would help if I could see pictures of the whole tank because the website picture is pretty poor - that will help me decide what lighting I can use. What would your plans be for this monster tank?
