Super Blue Kerri Tetra – Your Ultimate Guide To A Dazzling Blue Shoal
Have you ever looked at your aquarium and felt it was missing that one special spark? That flash of brilliant, electric color that catches your eye from across the room? You’re not alone. Many aquarists search for that perfect centerpiece fish that’s both stunning and peaceful.
The super blue kerri tetra (Inpaichthys kerri ‘Super Blue’) is that spark. This little gem glows with an iridescent, sapphire-blue hue that seems almost unreal under aquarium lighting. It’s an active, shoaling fish that brings life and movement to any planted tank.
Imagine a shimmering school of these vibrant blue fish weaving gracefully through lush green plants—a living work of art you created. They are more than just beautiful; they are a joy to watch and relatively easy to care for, making them a fantastic choice for hobbyists of all levels.
In this complete guide, we’ll dive deep into everything you need to know to help your school of Super Blue Kerri Tetras not just survive, but truly thrive. Let’s get started!
What Makes the Super Blue Kerri Tetra So Special?
Before we get into the nitty-gritty of care, let’s appreciate what makes this fish a standout choice. It’s not just another tetra; it’s a selectively bred marvel that has captured the hearts of aquarists worldwide.
The standard Kerri Tetra is a lovely fish, but the ‘Super Blue’ variety takes its beauty to a whole new level. Through careful selective breeding, hobbyists have intensified the natural blue sheen, creating a fish that is almost entirely a solid, metallic blue. The males are typically more vibrant, while females have a more subdued, yet still beautiful, coloration.
One of the key benefits of super blue kerri tetra is their wonderfully peaceful temperament. They are ideal community fish that won’t bother their tank mates, making them a stress-free addition to a well-planned aquarium. They are active swimmers, but not hyperactive, adding a sense of calm energy to the tank.

The Ideal Aquarium Setup: A Super Blue Kerri Tetra Guide
Creating the right environment is the most important step in keeping any fish healthy and happy. Think of it as building their perfect little world. For the Super Blue Kerri, this means mimicking the soft, acidic, and tannin-stained waters of their native Amazonian habitat.
Tank Size and Why It Matters
While these are small fish, they are active and need swimming space. A single Super Blue Kerri is a stressed Super Blue Kerri. They absolutely must be kept in a group!
We recommend a minimum tank size of 15-20 gallons for a school of 6-8. A longer tank, like a 20-gallon long, is preferable to a taller one as it provides more horizontal swimming room. If you can go bigger, do it! A larger school in a 30 or 40-gallon tank is a truly breathtaking sight.
Water Parameters for Peak Health and Color
Getting the water right is crucial for their health and bringing out that incredible blue color. These fish prefer water that is soft and slightly acidic. Unstable water parameters are a primary cause of stress and disease.
- Temperature: 73-82°F (23-28°C) is their sweet spot.
- pH: Aim for a slightly acidic to neutral range of 6.0 to 7.2.
- Hardness: They thrive in soft water, between 2-12 dGH.
Don’t worry—these fish are perfect for beginners! You don’t have to be a water chemistry expert. Using driftwood, catappa leaves (Indian almond leaves), or peat in your filter can help naturally lower the pH and soften the water while releasing beneficial tannins that these fish love.
Substrate, Plants, and Decorations
Here’s where you can get creative and build a beautiful, functional home. A dark substrate, like black sand or dark gravel, will provide a stunning contrast that makes their blue colors pop. A light-colored substrate can wash out their appearance.
Ample planting is a must. Live plants provide cover, make the fish feel secure, and help maintain water quality. Good plant choices include:
- Java Fern
- Anubias
- Amazon Swords
- Cryptocoryne species
- Floating plants like Frogbit to diffuse bright lighting
Adding driftwood and leaf litter not only looks natural but also helps create that blackwater environment they adore. This is a simple step towards an eco-friendly super blue kerri tetra habitat that mimics their natural world.
Your Comprehensive Super Blue Kerri Tetra Care Guide
Once the tank is set up, the day-to-day care is straightforward. Following a consistent routine is one of the most important super blue kerri tetra best practices you can adopt. Consistency is key to a healthy, thriving aquarium.
Feeding Your Shoal a Balanced Diet
A varied diet is essential for vibrant colors and long-term health. These tetras are omnivores and not particularly picky eaters. A high-quality micro-pellet or crushed flake food should be the staple of their diet.
To really see them shine, supplement their diet 2-3 times a week with frozen or live foods. They go crazy for:
- Daphnia
- Baby brine shrimp
- Bloodworms (as a treat)
- Blackworms
Feeding a variety of foods ensures they get all the necessary nutrients, which directly impacts their coloration and energy levels. This is one of the most effective super blue kerri tetra tips for enhancing their famous blue hue.
The Importance of Shoaling
We can’t stress this enough: do not keep this fish alone. Super Blue Kerri Tetras are a shoaling species, meaning they find safety, comfort, and confidence in numbers. Keeping them in a group reduces stress and encourages their beautiful, natural behaviors.
A minimum school of 6 is required, but a group of 10 or more is highly recommended. In a larger group, you’ll see more interesting social interactions and the males will display their best colors to impress the females.
Routine Maintenance and Water Changes
A clean tank is a healthy tank. A regular maintenance schedule is non-negotiable. Plan on performing a 25-30% water change every week. This helps remove nitrates and replenishes essential minerals in the water.
When you do your water change, use a gravel vacuum to clean a portion of the substrate. This removes waste and uneaten food before it can break down and foul the water. Always remember to treat new water with a dechlorinator before adding it to the tank!
Choosing the Perfect Tank Mates
Thanks to their peaceful nature, Super Blue Kerri Tetras are fantastic community members. The key is to choose tank mates that are similar in size and temperament and share similar water parameter requirements.
Excellent Tank Mates Include:
- Other small tetras (Neons, Cardinals, Rummy Nose)
- Harlequin Rasboras
- Corydoras Catfish (for the bottom level)
- Otocinclus Catfish
- Dwarf Gouramis
- Peaceful Apistogramma species
Fish to Avoid:
- Large, aggressive fish like many Cichlids.
- Fin-nippers like Tiger Barbs.
- Any fish large enough to see a tetra as a snack.
Pro Tip: Always quarantine new fish in a separate tank for 2-4 weeks before adding them to your main display. This prevents the introduction of diseases that could wipe out your established community.
Common Problems with Super Blue Kerri Tetra (and How to Solve Them)
Even with the best care, you might run into an issue or two. Knowing what to look for is half the battle. Here’s a quick guide to troubleshooting some of the most frequent challenges.
Faded Color
Is your brilliantly blue tetra looking a bit pale? This is a common sign of stress. The most likely culprits are poor water quality (check your ammonia, nitrite, and nitrate levels!), incorrect water parameters, bullying from tank mates, or an insufficient school size. Address these core issues, and their color should return.
Disease Prevention
The best way to deal with disease is to prevent it from ever starting. Common freshwater diseases like Ich (white spot disease) and fin rot are almost always linked to stress and poor water conditions. A stable, clean environment and a high-quality diet are your best defenses. Learning how to super blue kerri tetra care properly is your number one tool for prevention.
Shy or Hiding Behavior
If your fish are always hiding, it’s a sign they don’t feel safe. The two most common reasons are:
- The school is too small. Add more of their kind to boost their confidence.
- Not enough cover. Add more plants, driftwood, or floating plants to give them places to retreat to. A fish that knows it can hide is a fish that will come out more often.
Breeding and Sustainable Super Blue Kerri Tetra Practices
Breeding these tetras can be a rewarding challenge for the dedicated hobbyist. It typically requires a separate breeding tank with very soft, acidic water (pH 6.0-6.5), dim lighting, and fine-leaved plants like Java Moss for the fish to scatter their eggs on. After spawning, the parents should be removed as they will eat the eggs.
More importantly, let’s talk about being a responsible fishkeeper. When you decide to purchase these fish, you’re supporting an industry. We encourage you to seek out a sustainable super blue kerri tetra source. This means buying from local fish stores with healthy, well-cared-for stock or from reputable private breeders. Healthy, ethically raised fish will acclimate better to your tank and live longer, happier lives.
Frequently Asked Questions About Super Blue Kerri Tetra

Why are my Super Blue Kerri Tetras not schooling together?
If your tetras are scattered and not shoaling, it can actually be a good sign! Fish school tightly when they feel threatened. If they are spread out and exploring the tank independently, it often means they feel safe and comfortable in their environment.
