    Standard Tank Dimensions

    I know tanks come in a vareity of volumes, but are there certain standard dimensions? For example, I have a 90g which is 48 x 18 x 24.

    The reason I ask relates to minimum volume for various fish. I would like to get a tang, but not a yellow. Some tangs require a minimum 100 gallons. My first instinct is to say 90 is close enough to 100. However, if the standard 100 is 60" long, then length would seem a more appropriate measure than volume.

    For most tanks that are not custom made for a particular propose there will not be much different because 2 - 100 gallon tanks will still have the same cubic feet of inside space. It is a minor issue.

    Thanks OSD, I wont try to make the fish fit the tank then. I have been researching various fish and often use liveaquaria as source for minimum tank size.

    Like some others on the board, I will just supersize my tank when we build our new house. Already have the land.

    Also keep in mind that any tank is never full to the brim and the gallonage quoted is alway for a FULL tank. So your 90 might really only hold 80 gallons.

    True. Should the volume in the tank also be adjusted for live rock? This reduces the actual free water column. Assuming so, then I would adjust down to reflect true swimming volume for the little fellers.

    yes .. if you have fish that require large swimming areas then it would make no sense to over fill the tank with more rock then is needed to do the filtering and decor. Yes the water volume is reduced by everything that goes into the tank.

    Thanks alot OSD. Right now I have 100# of LR. I am going to add another 25 - 30 lbs. Probably just cherry pick where I can to improve the decor.
