The hobby of aquarium keeping and tropic fish as pets is fairly recent in the Western World, and took a while to catch on. The keeping of fish in small indoor tanks was only seriously considered in the middle of the last century, when both in Britain and the rest of Europe a considerable interest in the subject developed.

At the beginning of the 1900’s aquarists around the world began to keep tropical fishes, and it was the "trend" of so doing that started a new wave of popular fish culture (keeping fish as pets).

The older aquarists were obsessed with copying nature in their tanks—or rather with the attempt to try and copy nature—whereas the keepers of warm-water fishes had to experiment and create suitable environments for them.

Often, they started only with the knowledge that the fish must be kept warm, and this in itself raised problems, including the death of favourite weeds and water snails at higher temperatures.

So, the aquarium gradually came to be regarded as most of us see it today, as a beautiful display, not a mirror held up to nature.

However, until the keeping of tropical fish, it seems that aquarists in general thought that the proper aim of an aquarium keeper was to reproduce a segment of nature.

Tropical Aquariums are for keeping tropical fish, but you can have two different types of fish, saltwater or freshwater. Saltwater fish obviously needs saltwater and the salt needs to be a regulated level along with the PH and temperature. Freshwater fish need to have fresh purified water, both of these set ups need the good bacteria that helps to keep the aquariums clean.

Tropical aquariums that contain saltwater are only for saltwater fish. If you put a freshwater fish in this tank it will die! Saltwater fish are made to stand the levels of salt and are essential for the fish to breath and move. If salt wasn’t present, they would die a death like suffocation. In saltwater aquariums you need to make sure that there are living rocks in it, this means rocks that already have the good bacteria present. You then need to leave the rock in the tank for at least two months before putting any fish in, this is to get a bacteria cycle on the go. Once the bacterium has built up, I set up the filter. After that it is safe to add the fish.

Freshwater tropical aquariums are for fish that need clear and clean water. This water has to be chlorine and ammonia free. The freshwater tank also needs to be set up and cycling for at least four weeks before adding any fish to it, as this will help the bacteria to build and make sure that the ammonia levels are kept to a bare minimum, ammonia is a substance that will kill our fish as it makes breathing for them very hard to do. You know when your tank has very high levels of ammonia because the fish are at the top of the tank struggling to breath but the trick is not to change the water, what to do is clean out the filter in some of the tank water (in a separate bowl of course) and then put it back in within a day or so. The water will be in a completely better condition. Purchase a water test kit to check your levels or nutrients before putting in your fish, they are not expensive but are a great help.

Tropical aquariums are stunning ornaments in any household! Just make sure that you don’t forget about the work and responsibility involved, they may be fish but they are still alive and should of course be kept that way!
