Talking about its size, these tetras grow up to 2 inches (5 cm) in the home aquarium. However, in its natural habitat, it can reach up to 3 inches (7.5cm) long.

Bentosi White Fin Tetras are often confused with the Rosy Tetra as they are very similar to each other in coloration and appearance. In their natural habitat, these two fish are close relatives.

Fish Keeping Difficulty

Bentosi White Fin Tetra is a moderately hardy fish. Any fish keeper with minimum experience can keep the fish. So, if you are at an intermediate level, you can undeniably go for this species without thinking twice.

In contrast, these tetras do not do well with the changes in water parameters. Hence, they need more pristine water. Although, some specimens which are captive bred are more tolerant and strong.

Hence, these tetras are moderately hardy and require an intermediate aquarist experience level.

I have written more about it in ‘ Are Tetras Hardy Fish? – Different Parameter Levels’

Foods and Feeding

The Ornate Tetras are omnivorous fish with a varied appetite. Since it requires high vitamin levels, flake foods are one of the major parts of their diet. Besides, you can feed them flake foods from 60 to 80 percent in their diet.

As these tetras are omnivorous, they prefer to go after live foods. This can even include live plants or algae. Get to know more about it from ‘Do Tetra Fish Eat Algae? – Should You Add Algae To Their Diet?’

You can feed them several times a day, but you have to be careful of how much you feed them. I suggest you offer the food that they can have in 3 minutes or less when you feed them.

Moreover, you can also feed them tablets or pellets which you can find in the market. The tetras will also prefer live foods from fish, shrimps to worms but make sure it covers only some of their diet.

Moreover, you can provide ornate tetra vegetable food that you have at home by cutting them into small pieces. Similarly, meaty food is also something that you can give to your Ornate tetra in a limited amount.

Here is a list of food that you can give to the Bentosi White Fin Tetras with the best ones that I would suggest-

Aquarium Care For Bentosi White Fin Tetra

Aquarium care for the Bentosi White Fin Tetra is not that hard. Since these tetras like clean and stable water, they are not difficult to care for if this part is taken care of.

You have to maintain your aquarium and keep it clean regardless of its size or closed systems. Besides, evaporation in an aquarium leads to decomposing organic matter, nitrates, water hardness, and phosphate.

For maintaining your fish tank, you have to replace or change 25 percent to 50 percent of the water regularly. This does not mean it should be changed daily, though. Do not change your tank water daily!

A Bentosi White Fin Tetra’s tank will need a partial water replacement every other week. You should clean the tank, especially if it is densely populated!

Aquarium Setup For Bentosi White Fin Tetra

The aquarium must be set up in such a way that a fish is comfortable. Likewise, the main focus here is to make the aquarium as close to the real natural habitat as possible.

Tank Size

For a Bentosi White Fin Tetra, a 15 to 20-gallon aquarium is best. The minimum requirement is a 15-gallon tank. However, you can increase the size if you get more of the tetras. They are schooling fish. So, a school of 6 is best for the suggested aquarium size.

The best aquarium you can get at an affordable price is Tetra Aquarium 20-Gallon Fish Tank Kit, Includes LED Lighting and Decor.


To set up the aquarium, you have to keep in mind to keep the filters at a certain angle to avoid disturbance. It is because these tetras do not do so well with fast-moving currents.

Lighting And Decoration

These tetras prefer dim aquariums as they live in the dense forest canopy in their natural habitat. Thus, I prefer Tetra Hidden LED Stick Light for Aquariums, Brilliant White.

Moreover, if you want to keep your Bentosi White Fin Tetra happy, you might want to plant around the sides and back of the aquarium. Make sure you leave proper open water for swimming in the front.

Water Conditions

Water conditions are an essential part of any fish tank to thrive. You should maintain a water hardness of 3 to 12 dGH. Similarly, a pH range of 6.6 to 7.2 should be maintained if you have caught the fish in the wild. If not, the 6.6 to 7.8 range will do. However, there should be no brackish water.

A better overview of such conditions is given in Water Parameters for Tetra Fish: Stable Water Condition.


You should maintain a temperature of 73.0 to 82.0° F (22.8 to 27.8° C) for the normal Bentosi White Fin Tetra to be comfortable. On the other hand, you might want to increase the temperature to 75 to 78.8° F (24 to 26° C) for breeding.

Sex: Sexual differences

Any fish enthusiast knows the basic difference between male and female fish despite the species. The female Bentosi White Fin tetra has a shorter and plumper body as most female fish do. Similarly, males have longer fins compared to female ornate tetra.

Breeding / Reproduction

The breeding process of a fish is the best part for a fish lover. Although it can be a little difficult, you can find it equally rewarding!

You will vision no care as a parent from these tetras. Your Bentosi White Fin Tetras will just scatter the eggs while spawning. Besides, such spawning will occur in a community tank with compatible breeding pairs in the right conditions.

Tank Size And Water Conditions

Like neon tetras, these tetras will also eat their eggs and fries. So, you will have to make a separate fry tank of about 10-gallons. Then, you can set up a temperature of 75 to 78.8° F (24 to 26° C).

Similarly, the water conditions include a pH of 6.5 to 7 and hardness of 4° dGH or less. Hence, it means that you can set the water slightly acidic but soft in nature.

Set Up A Breeding Tank

Next, to set up a breeding tank, you should add up plants with fine leaves. It would be best if you keep the lights dim and have a gentle current of water flowing in the tank.

This is to make the tetras feel at home and trigger their spawning. Moreover, you have to understand that the spawned eggs are also light sensitive.

For equipment, you will want an air-powered sponge filter. A small one will help you filter, oxygenate, and keep the water in a gentle flow.

The plants with fine leaves are the place where your Bentosi White Fin Tetra will release eggs. Firstly, they will spawn in the morning. Since the parents will eat their eggs and fry, you have to immediately remove them from the tank.

The spawned eggs will hatch in 24 to 36 hours approximately. Likewise, your fry will be swimming freely after 5 days.

Besides, you should change the water frequently in the tank. However, make sure you do not remove any fry in this process.
