# How to find out how many gallons a hexagonal tank is?

Tom
Does anyone know how to find out how many gallons a hexagonal tank is?
Tom

Not other than to fill it. Sorry.

what does the water dept, sump shape, and prop. tank mean?

I you click the drop down arrow on the left and choose hexagon it ashs for depth add width. Put those measurements in and calculate. All you need is the top line. The others are for tanks that have those things.

What does the sump shape, and prop. tank still mean though?
Tom

Butterfly
Some tanks have sumps or other additions connected to the tank, this helps figure out total water volume by counting what's in them also.
well how much water does the hex hold
Carol

Tom
28.1 Gallons. And my other is 35.5 Gallons. They are larger than I had orignally thought. ;D

My Clowns went from 1-1/2 inches to 6 inches in a year and have slowed down since. don't know about the rest.

If you want to know how to do it manually then you'd have to know a little geometry. Basically all you need to do is find the area of the hexagon in square inches then multiply that by the height of the tank in inches. At that point you'd have cubic inches of water volume which you can then convert to gallons. To find the area of a hexagon you need to find the area of one isosceles triangle then multiply it by 6 or the area of 1 right triangle then multiply by 12.

Can I jump on this thread? I hope this isn't rude... when I'm searching the ads for used tanks, I usually find hex tanks, rather than rectangular ones for sale...is there a problem with hex tanks? too hard to keep clean, or visually are they less appealing in some way, or what? just wondering.. thanks!

In my opinion, the hex is less appealing because the fish are used to swimming from one long side to another. The hex is great for keeping angels though because they are tall and like deep water in the wild. Also you would need a long intake tube for the filter to reach the bottom or you could have high nitrites and nitrates, as well as a pretty strong filter to circulate all the water clearly. And with the hex tank, there will be less oxygen reaching the bottom, which will lead to fewer fish (I read this in a book). Hope this helped with your decision.

There ok for smaller tanks for something different but yes like everybody else has said they are not as practical. Tomh it would be better to get a 29 gallon tank as it's 18" tall or a tall tank rather then a hex IMO

I got the tanks from my uncles for free so I'm not complaining. ;D And there isn't much you can do if it for free and you need it to put platy fry in.
Tom

Well if it's free all for it, though usually there more expensive so unless you lilke them they aren't the greatest thing to buy.

Tom
I agree. The lfs that I go to regularlly only sells the canopy for the hex tanks and not the hex tanks themselves.

My favorite types of tanks are long tanks because they look bigger than they are and can have more fish because of the extra surface area if you filter correctly, bowfront and hexs look cool but I like keeping more fish.

Tom
Amen to that. lol

The reason why I personally don't like hex tanks is because they have those corners which kinda distorts the view. With a flat or bow front the view isn't distorted.

Tom
And it makes it look like there are more fish than you really have.
Tom

I like my Hex's for my Bettas and they seem to like them too. They do a lot of vertical swimming but they also have a lot of room to swim back and forth at the top. I take pictures of them all the time and you just have to be careful of the angle and otherwise I do not find them distorted. It is all in what you are looking for. For a tank where you are basing it around one fish, I think they are excellent. Perhaps, for a community tank I can see why they would not be desirable.

Agreed Rose though 2.5 gallon hex's aren't probably that great for bettas as a 5 would because of the surface area, I think they are cool like you said for one fish or so, there a cool design.
