Aquariums have to be made of toughened glass because this glass has to bear a lot of pressure with a full tank of water, accessories and the fish. If the glass is not strong enough it can just give way and all the fish and everything in the tank will end up on the floor. The glass is also very heavy and there is no way anyone can pick it up once it is filled up with water and fish etc. This is the reason that an aquarium stand is used, and the tank should be put on this and then filled up. Glass fish tanks are available in various sizes and shapes too. If you want a table top one you can get a fairly small one, but if you have space enough for a large one you can stand it on an aquarium stand and opt for the bigger sized ones. A lot depends on the space you have and the kind of fish you plan to keep in it.
The glass for an aquarium is thick and strong
Some of the aquariums are pretty large being almost nine to ten feet long and over 3 feet wide so you can imagine how much pressure there will be on it with that amount of water. Though the glass is sealed on the sides it still has to be very strong and thick so that it does not crack with the pressure and spill the contents out. For the safety of the people around and the fish in the tank the glass is made as strong as possible.
Acrylic fish tanks
Acrylic is twice as strong as glass and yet weighs much less. Fish tanks made of acrylic are much stronger than those made of glass. When heated acrylic can be moulded into any shape and this way you can get a fish tank of any shape made of acrylic and further more as the edges do not have to be sealed this tank is much stronger than one made of glass. However glass fish tanks are still more popular and not many go in for acrylic tanks.
The glass aquariums are pretty expensive but easily available and you could have one built to suit the size and shape you want, you do not have to buy one off the shelf only but can have it made to order. Of course if you can build your own tank then nothing like it, but you have to make sure that it is made strong enough.
