How To Choose Fish For A Tropical Fish Tank

This film will show you how to select fish for a tropical aquarium. It will help you decide which types to choose and how many to keep in your tank.

Step 1: You will need

  • A fish retailer, with a good selection of fish to choose from
  • and an aquarium. Watch VideoJug's film "How to set up a tropical fish tank"

Step 2: Deciding how many

The type and number of fish you can keep will depend on the size of your tank. An easy formula for calculating how many fish you can keep is to multiply the length of the tank by the width to get the surface area, and then divide this number by 30. For example, a tank length of 90cm multiplied by a width of 30cm equals 2700 square cm of surface area. Divide this by 30 and you get 90. This means the tank can hold tropical fish with a total length of about 90cm.

Step 3: Different types available

There are a vast number of tropical fish species available for keeping in aquariums. Some of the most popular species include:
Siamese Fighting Fish and of course the iconic Angelfish.

Some of the larger and more specialised varieties include Pufferfish, Arowanas and Piranhas, which have a fearsome reputation. Watch VideoJug's film called 'How to care for Piranhas'.

When placing aquarium fish of different species in the same tank together, known as a community tank, it is important to choose species that are known to be compatible and will not eat each other.

Fish question

by Ivarsgirl

I'm fairly new to keeping tropical fish but I love it :)
I have guppies, danios, mollies and plecos together in a tank. I noticed today at petsmart the guppies and mollies had a note "requires aquarium salt" but the danios and plecos did not. I picked some up.
I assume the plecos and danios will not be harmed by the salt if I put it in for the benefit of the others - but you know what happens when you assume.
Anyone out there know if it's OK to put it in?

Easy in a way...

It is easier to care (longterm) for a larger tank than a smaller one, but it still takes work.
First, don't mix tropical fish and turtles. They have different needs (in terms of tank set-up) and anyway, the turtles will just snack on your fish. So figure out what you want in the tank first.
Starting a new fishtank takes a bit of time, because you shouldn't just go out, buy a tank and some fish and set it up all at once. Talk to some people at aa aquarium specilty store (please not a petsmart kind of place-they are clueless) an they will help you figure out your equipment needs, tank set-up etc.
