The practice of keeping aquariums came about in the late 1800's. They were fairly crude. These ancient aquariums only had one side that was made from glass, with the other three sides being made of metal or wood. Most aquariums contained fish that were indigenous to the location of their owner due to availability. Also most old school fish tanks contained only freshwater fish. This is because salt water would corrode the metal frame that held the aquarium together.

Aquariums drastically changed in the 1960's with the advent of silicone adhesive. Metal frames became obsolete and more people started to keep salt water fish and invertebrates. More recently glass tanks have become less often used due to the flexibility of acrylic. Acrylic fish tanks are much more forgiving compared to their glass counterparts. If a heavy object strikes a glass tank, it will likely break. The flexibility of the acrylic tank prevents this catastrophe from occurring. Additionally, acrylic provides more flexibility in design than glass. Acrylic aquariums have been made into everything from coffee tables to gum ball machines.
That said, there is a short downfall to possessing an acrylic fish tank. They do scratch easier than glass. When cleaning your aquarium, be careful not to use paper towels, and harsh or abrasive chemicals, as they can scratch the acrylic surface of the aquarium tank. Always use a cleanser specifically labeled safe for acrylic. Use plastic or rubber scrubbers, rather than metal to clean the sides of an acrylic tank. Take care not to accidentally pick-up a bit of substrate or gravel while washing the inside of the tank. However, if you do happen to scratch an acrylic aquarium tank, all is not lost. The tank may be repaired, unlike glass. There are actually acrylic repair kits available at specialty pet stores, the local hardware store and of course on the internet.
When purchasing an acrylic aquarium kit, there will be many different options to select from, at many different price points. Aquarium kits can be purchased at places such as specialty aquatic pet retailers, from big retail chains, or again online.

While, there are some basic things that'll be contained in most aquarium kits, for example, a filter, some substrate or coral and sometimes lighting, the kits themselves can vary greatly. It doesn't matter where you buy your basic starter kit, but remember that it is extremely important to purchase your fish from an established dealer. Do not buy fish that are hovering near the surface, or which are located in an aquarium with other dead fish. Fish diseases are incredibly communicable. Be weary of any fish seller which will not catch a particular fish from the tank for you. After all this is going to be your fish and you've got the right to pick.
