There is actually a quite big list when it comes to tetras and the same is when it comes to one definite color.

Not that color makes them any different from other tetras except in color, red will definitely add new life to your tank.

I can’t argue the fact that red will look so beautiful and heart-warming in the home aquarium. So, now from this chit-chat to the main thing, we are talking about today.

Here is the list of 12 red color tetra fish for your aquarium; trust me they will bless you with their presence.

Ruby Tetra

Red Color Tetra

Ruby tetra is the first one on the list with its beautiful features and body making you fall in love with it every time.

This perfect red-pigmented tetra has a small yet ruby red-tinted body along with transparent fins. However, there is a little hint of black in the back of the tail adding additional beauty to this fish.

The red color might pop a little more in the wild than in captivity. When you hold them in the home aquarium, Ruby Tetras tend to get stressed so, you might see a little faded red color as well as orange too.

But don’t worry the color will be back as soon as they adjust to the new parameters but make sure it is ideal for them.

Ruby Tetra as their name suggests, has this beautiful and vibrant Ruby red color in their body. Hence, a different shade of red to choose from.

Serpae Tetra

Red Color Tetra

Now, coming to the second red color tetra, I decide to go with Serpae tetra. But footnote the numerical arranging has nothing to do best, all of the tetras listed here are the best of the best.

So, none of them hold a candle to being the very best of the rest. Since, I have made this clear, hope you won’t judge the tetra according to the number.

Coming back to the Serpae tetra, as you know now already are reddish in color. However, the color present in the tetra doesn’t end here, you’ll see a hint of brown to black when it comes to Serpae tetra.

They have so many names that indicate the color red abundantly, a few of them are blood tetra, red minor tetra, jewel tetra, blood Characin, Red Serpae, etc.

They have the most noticeable color deep reddish shade that looks so beautiful and vibrant under aquarium lighting.

However, behind the gills of Serpae Tetra, you will find a comma-shaped black dot adding extra vibrancy.

The fins, although, tell a different story; the dorsal fins have a whitish color with a black tip.

However, the other fins present in the Serpae Tetra are exceptionally red while the edge of the anal fin is black with a splash of white.

Ember Tetra

Red Color Tetra

Well, we are in the third tetra and hence Ember Tetra sweeps the position smoothly with its vibrant and beautiful color.

You will know them from afar in the aquarium thanks to their easily identifiable appearance. The color plays a vital role in making ember tetra attractive for your aquarium.

The fiery red color along with a few cases of the saturated orange gradient, ember tetra definitely steals the show.

Also, you will see a hint of orange color around the rim, making the eyes pop, hence a desirable fish for an aquarium.

Flame Tetra

We are now on our fourth tetra that has a red color in their body and there is a high chance they got their name from the same thing too.

I am talking about flame tetra, the tetra that resembles the color of fire and its flame. You can easily contemplate the color of the flame of flame tetra by just thinking of the flame.

Starting with the shade of gray and the sides of bronze, it leads to the red followed by brighter red to the end.

Gray, bronze, yellow, black, and red are the colors that make flame tetra beautiful and attractive. The first half of their body, the head region, is gray leading to the bronze color.

Likewise, the other half of the body is lighter red while the shade grows darker red, and hence the fin is the brighter red.

However, the anal fin of male flame tetra is quite brighter than female flame tetra. The anal fin of female flame tetra is somewhat a lighter shade of red and sometimes yellow too.

Furthermore, the tip of the anal, as well as the pectoral fin, is black in females however the black tip in the pectoral fin is absent in males.

There is, however, a chance of you meeting the flame tetra with faded color when you visit the pet store. It is due to the stressful environment.

These tetras will gain their color back once they are in an aquarium with appropriate water parameters and an ideal environment.

Bleeding Heart Tetra

Bleeding Heart Tetra

While we are talking about red color how can we leave behind the tetra that carries the bleeding-heart shape on its body? The fifth tetra on the list of red color tetra is the Bleeding heart tetra of course.

The most exclusive and important feature of bleeding heart tetra is the heart-shaped red patch present on the side of their body near their gills.

Thanks to this very patch for giving bleeding heart tetra their most famous name as well as making them unique.

The color range of bleeding Heart tetra has a combination of beige orange to silvery lavender.

All of these shades of red make these tetras astonishingly beautiful and an ideal choice for your aquarium.

The color of bleeding heart tetra is the rosy silver hue to be precise but that remains only on its body. The tailfin, pectoral fins, and anal fins of these tetras are, however, transparent.

But the dorsal fin is quite different than other fins with the splash of red and black adding another color to the list.

Bloodfin Tetra

Bloodfin Tetra

Coming to the 6th one in the list, we will be talking about a tetra with unique fins i.e., Bloodfin tetra.

The body of these tetras might not have a hint of red in it and is completely silver. Hence, the primary color of bloodfin is silver however the color varies when it comes to their fin.

The dorsal, anal, adipose and tail fins have vivid red color and their stark contrast to the other part of the bloodfin tetra’s body.

However, the tips of the fins don’t have the same red color and are transparent usually. Hence, the name of this very tetra is named after their blood-red fins i.e., Bloodfin tetra.

Red Phantom Tetra

Red Phantom Tetra

The position of lucky seven in the list of red color tetra fish is hence taken by Red phantom tetra.

The coloration and shape of Red Phantom Tetra resemble several species of the same genus like Rosy Tetra, black phantom tetra, and Serpae tetra.

However, the black shoulder patch and white edges in the fins are present in Red Phantom Tetra, unlike others.

They have a red transparent body with black dorsal fins with white tips in females making it an ideal red color fish for your aquarium.

The color tends to vary according to the diet and environment your Red phantom tetra is in, so make sure you don’t let the color fade due to carelessness.

Scarlet Red Line Tetra

Scarlet Red Line Tetra

The 8th position is taken by one of the rarest tetras in the market although has a very prominent red color. We will be talking about Scarlet Red line tetra in this section specifically.

Although they don’t have well-known names these tetras are often referred to as watermelon tetra, red laser tetra, and Coreulean Pink Tetra.

You can clearly see each of their names has a hint of red color. And the vivid red coloration with a neon pink line on the downside of their body makes them way more attractive.

Scarlet Red Line tetras look spectacular when they enter the spawning period. You see the male scarlet red line develops a deep ruby red color making them get confused for some other species.

They have this undeniable resemblance to glowlight tetra apart from the color and other few features. This is maybe due to the same genus name of both these tetras.

Red Line Tetra

Here we are in the 9th one from the list and I placed our Red line Tetra in this position just after the Scarlet Redline.

People often get confused with Scarlet Red line tetra and Red line tetra due to the similarity in their names.

Also, another name of red line tetra is scarlet tetra, but as I said these two tetras are completely different.

Redline tetra got its name from the red line that runs below the head to the end of its silver color body.

These tetras body is a combination of various colors such as yellow, grey, black, silver, and red.

Right behind the head of the Redline, you will see a black mark that is small yet prominent.

You will also see another line yellow in color running just below the red color in their body.

Additionally, the upper part of the eye has a hint of red color making its eye pop with vibrancy.

The color of these cardinal tetras is a combination of red and blue. While the blue color strip sits on the top side of the cardinal tetra’s body, the red color runs on the lower side of the body from head to tail.

These two colors are so bright that the school of these fish swimming around the tank is way more attractive.
