Starting a new fish tank?

Want to know more about tropical fish?

There are many, many choices when it comes to tropical fish, but what should you get?

In this Guide to 101 Tropical Fish I will outline 101 different tropical fish with a little information on each so that you select what is right for you.

Let’s get into it!

Before you do anything, there are a few things you need to consider first before buying your fish.
In particular, you need to ask these questions:

How large do they get at adulthood?

How aggressive are the fish? Will they get along with others?

What do they eat? Meat, plants, other fish, snails or a combination?

What are their habitat preferences? Do they require a school or hiding places? Bottom, middle, or top dweller?

Are they susceptible to diseases? If so, what kind?

Are they difficult or easy to keep?

As a general rule, you’ll want a combination of top, middle, and bottom dwellers. If you’re mixing species and are a beginner, then you want to stay with smaller ‘community’ fish that are hardy. What’s known as community fish are peaceful and generally get along well.
