Types of Tropical Fish

Types of Tropical Fish – warm-water fish. Certainly one of the many small tropical fish kept in aquariums. They’re also interesting because of how they act or show off. Popular species include angelfish, guppy, kissing gourami, sea horse, Siamese fighting fish, and tetra.

Below, I’d like to discuss the various tropical fish that exist in both freshwater and seawater. I’ll demonstrate and discuss some examples. Especially for aquarium enthusiasts looking for one-of-a-kind specimens.

Types of Tropical Fish – Tropical freshwater fish

Of course, there is a plethora of tropical freshwater fish that can be classified into 25 different groups. I’ll give you an example from each category here.

Category 01: Algae Eaters: Hypostomus Plectomus gold strip

People refer to catfish in the Loricariidae family as “suckermouth catfish.” It has 92 genera and over 680 species, but only a few are commonly kept as pets.

This type of fish is commonly found in tropical community fish tanks. It’s also known as a plecostomus or a pleco. They can cling to rocks, wood, or the sides of your aquarium by sucking on them.

When you see a group of clown loaches, it’s hard not to want to take a few of them home. This magnificent, foot-long fish is a food item in Indonesia and Borneo.

But, the clown loach is lucky that aquarium owners keep them in the community tank and not on the dinner table. Especially its orange and black stripes, red fins, and energetic character make it a popular loach species.

Category 04: Cichlids: Nimbochromis venustus / Malawicichlid venustus


In fact, there are at least 850 species of cichlids in Lake Malawi. Most of them come from Africa and Latin America. That’s more fish species than all the freshwater lakes and rivers in Europe put together.

Category 05: Corydoras: Corydoras Albino

Corydoras Albino

Approximately 240 species are known at this time, but only about 30 of them are regularly available in the aquarium trade.

  • Firstly, this is a calm fish that swims in groups.
  • Secondly, keep them in a school of good size, or they won’t feel good.
  • Thirdly, keep at least six copies for them, but a lot more is better.
  • Fourthly, these fish like to go down deep, which is a cool thing to see.

Generally, they live in community aquariums because they can coexist with most fish, with the exception of large fish that eat other fish. As a result, the minimum length of an aquarium is 80 cm.

Category 06: Danio’s: Celestichthys margaritatus / Galaxy rasbora

Galaxy rasbora

So, If you’re new to fish tanks or want a gorgeous, quiet fish, choose the “Galaxy rasbora”. Furthermore, this species is hardy, easy to care for, and gets along with just about any other peaceful fish.

Most sharks are too large to fit in a home aquarium. It is about 41 inches long and can live in a large 180-gallon tank with other fish who get along with it. In captivity, it usually thrives.

The only serious problems with keeping these sharks are feeding and health. You may need to “target feed” your shark to ensure it gets the proper food and medication to stay healthy.

Category 14: Labyrinth Fish: Betta splendens male super delta / Siamese fighting fish male super delta

Siamese fighting fish

A labyrinth fish is one that has a special organ called the labyrinth that allows it to breathe air from the water’s surface. But, fish live in water, so why would they require an organ to breathe air?

Because of the environment. Some fish live in areas where the water is or can become depleted of oxygen. So, in such environments, having a labyrinth organ can mean the difference between life and death for fish.

Category 15: L numbers & Ancistruses: Peckoltia vittata / L103-peckoltia vittata

Types of Tropical Fish – Top 10 saltwater fish

Of course, If you want to start with a saltwater aquarium but do not yet have enough knowledge, it is better to start with easy-to-keep fish. These fish really don’t demand anything special and are still fun to keep and especially to look at.

Following are the top 10 fishing for beginners.

Saltwater Fish 01: Clownfish (Amphiprion Ocellaris) (remember “Finding Nemo“…)

Clownfish (remember “Finding Nemo“…)

In their natural habitats, clownfish and anemones have a symbiotic relationship. The clownish provides the anemones with nutrients they need, while the anemones protect the clownfish from predators.

On the sides, there are a few vertical stripes that fade into the dark background. On a light background, these stripes stand out more.

This fish can change its color and pattern on its body a little to fit in with its surroundings. This helps it hide well. Large reddish-green eyes high on the head stand out. Above the eyes, there are things that look a bit like antennae.

Saltwater Fish 04: Yellow Surgeonfish (Zebrasoma Flavescens)

Yellow Surgeonfish are solid-colored, unlike most surgeonfish. Night or when threatened, their color changes.

Without a doubt, the Flame Angelfish (Centropyge loriculus) is one of the most popular dwarf angelfish among both new and experienced saltwater aquarium keepers.

The bright red and orange color of this fish, the black vertical stripes on its body, and the blue tips on its dorsal and anal fins make it the star of any marine aquarium.

It is interesting to see how the Flame Angel’s colors and markings change depending on where it is found.

Saltwater Fish 07: Gramma Loreto

Gramma Loreto
King’s Gramma

The “King’s Gramma” has a slender torpedo-like body. Saltwater aquarists like them because they have three colors and are bright. The front of these fish is royal purple, and about halfway down the body, there is a red band.

The rear and caudal fin are bright yellow. This is one of the smaller species that can grow to be about 10 centimeters long when it’s an adult. In general, they live between 3 and 5 years.

Because the Gramma loreto is a royal purple color, it is also called King’s Gramma. He is called Royal Gramma in English, which is a name that is sometimes used in Dutch.

Saltwater Fish 08: Blue Mandarin pit fish (Pterosynchiropus Splendens)

The yellow or lemon wrasse is about 12 cm long and is a great addition to an aquarium. The fish don’t touch the coral, but they can eat small shrimp and crabs.

Saltwater Fish 10: Large Lionfish (Pterois Volitans)

Large Lionfish
Large Lionfish

All lionfish have fins with unique shapes and stripes on their fins and bodies. Depending on the species, size, and color range. Dwarf lionfish only grow to be 20–25 centimeters long as adults and can live in an aquarium that is only 150 liters in size.

Other species can go as long as 68 inches and need a 350- to 450-gallon aquarium. These toxic fish should only be kept by experts.

Also Important: What Do Tropical Fish Eat?

Young tropical fish need more feedings than adult fish. They eat pelleted, frozen, and freeze-dried protein. Tropical fish eat live food.

Fish can eat many things. Start with a healthy diet. You improve their mental wellness. Overfeeding fish is bad.

Overfeeding can cause poor water quality, obesity, and other health issues. To avoid overfeeding, watch your fish’s intake. Some species may need more than 2-3 minutes to eat.

You should also consider the type of eaters your fish are. Some fish eat from the top of the tank, others from the middle, and still others from the bottom.

Remove leftover food when your fish are done eating for the day. In this way, you prevent ammonia buildup.

Tropical Fish That Can Live Together

Choose fish that can live together if you want your aquarium to do well. But this can mean a lot of different things, like having only big fish that stay away from each other or a lot of aggressive fish that keep their relationships in order. So, it makes sense that I like peaceful fish that live in groups.

Most people who want to keep fish for fun should get a community tank, and there are lots of peaceful fish to choose from. But if you asked me to pick five fish that almost always get along, these are the ones I’d choose. (see below)

The word “almost” is important. It’s important to remember that we never know how different fish will get along in our tanks. You can use this as a starting point, but before you choose any fish for your aquarium, you should always do a lot of research.

Otocinclus Catfish, Zebra Danio, Neon Tetra, Fancy Guppy, and Cory Catfish are the names of these peaceful fish.
