Tropical Aquarium Fish

Fish that live in tropical waters are called tropical fish species.

In the beginning, you have a lot to learn. There are a lot of new words you need to learn about tank care and management, too. As you learn about aquariums, it can help you make better decisions if you know who the people in them are.

Stepping into a live-fish store tells you that this will be hard. Hundreds, if not thousands, of fish species are found in aquariums. People’s names are hard to remember. How are you supposed to remember their traits and the best ways to keep them happy and healthy?

It’s good to be able to group them by type. Related fish often (but not always) have the same traits and behaviors. Once you figure out what kind of fish you’re looking at, you can figure out what you can expect.

It’s easy to group these fish by family, genus, and species because they have official names. That’s not what this article is about, but you can look up those names if you want to.

Instead, I’ll use words you’ll see a lot as you learn more about fish keeping. As a rule, you won’t see Characin unless you look for it. You’re more likely to see tetra.

There are a lot of common fish species that fall under the type tetra. What are some of their most common traits? Then, keep reading to find out more.

Kryptopterus bicirrhis is a glass catfish (Family: Siluridae)

Behavior

The Glass catfish is shy and prefers to be in a small group with its kind, but it can live in a group aquarium. It’s a tropical fish that will grow about 11 cm long when it grows up. Sometimes, it rests on the bottom of the tank in the plants.

When someone leans to one side or puts their head down, they may look sick or dead. They aren’t, though. This is normal for them, and they will run away when afraid.

When the water and tanks are in good shape

25 to 29 degrees Celsius is the best temperature range for this fish to live in because it likes that kind of weather. Because it is shy, you need to make sure there are a lot of places where it can hide, whether that’s by plants or aquarium decor.

Feature and color are the main things to look at.

The most unusual thing about the glass catfish is that it is clear. When the light is just right, it will look like it’s not there. Other times, you can see its bones. Another thing that makes it unique is that it has two long barbels (whiskers) that come out from the front.

There is a big difference in fin size. The lower part of the caudal fin is more significant than the top one. Black spots on the fish’s flanks mean that your fish is sick. It would help if you did something.

Feeding

Sprinkle food on the surface, and this fish will eat it as it falls. It likes to eat small, live food.

Preparation for breeding

It looks like the Kryptopterus hasn’t been bred well in captivity.

This is Glass Tetra: Roeboides microlepis (Family: Characidae)

Behavior

The small-scaled glass tetra is a firm fish that can be argumentative and make a mess when it comes to feeding time. Keep an eye out for that. If you put it in a tank, it usually likes to stay near the bottom with its head down. It looks very different from the fish that wants to stand up.

Conditions of water

Standard tropical tank temperatures should be enough.

Feature and color are the main things to look at.

There are small scales on its back, long body, and mouth. It has a big mouth and a curved back. Adults can grow up to 10 cm. You can’t see its bones, so it isn’t an actual “glass” fish. The yellow body has a blue-green band on one side, and when the light is just right, you can see tiny shiny black spots.

Women have bigger bodies than men. When they are in breeding mode, their fins become darker when they are darker.

Feeding

It should eat a lot of food that is alive. Notice how it fights at feeding time, as I said above.

Preparation for breeding

Hard to breed, but not impossible. There have been reports of success, so it isn’t impossible to produce them. Due to their argumentative nature, it is essential to find and use a compatible pair. This will help the chances of success. It is also likely that conditioning and separation of the sexes before courtship will be good. A big tank is better, and you should know that the affair will be rough.

Octocinclus affinis – Golden Octocinclus (Family: Loricariidae)

Behavior

It’s also known as the Dwarf sucking catfish. Other species of the genus Ocycinclus are almost the same as the species described herein in virtually any way. Not all upside-down fish are like this, but this one is. The plant should be safe as long as the scavenger has a vegetable matter to try to eat.

When the water and tanks are in good shape

You’ll need a lot of foliage and places to hide to keep it out of the sun. Even if the temperature of the water drops, it can handle it if there’s enough oxygen in the water.

Feature and color are the main things to look at.

It will be about 4.5 cm long and have a long, brown body when it grows. It has a dark brown back with a lighter shade on the bottom and darker mottling on the top of the animal. All Octocinclus species don’t have adipose fins, so they don’t have any.

The female is a little bigger and fuller in the body than the male, but it’s not much. Scavenger: Its lips are used to suck food. As an armored catfish, its scales are made of rough bone plates. There are no big eyes on it, and its snout is curved.

Feeding

A lot of its favorite foods are vegetable matter and tubifex.

Preparation for breeding

If you want to breed this freshwater tank fish, there isn’t much information about how to do it. It has been produced in captivity, and reports say that sticky eggs were laid on the sides of the tank and that the eggs hatched in about two days.
