Every aquarist loves watching their fish glide through crystal-clear water, showing off rich reds, glowing blues, and shimmering metallic hues. But without the right lighting, even the most colorful fish can appear dull. That’s where CTT’s ColorBoost and Fish Color Enhancing LED lights come into play.
These specialized LED fixtures are designed to highlight the natural pigmentation of tropical and freshwater fish species, while also providing a comfortable and biologically suitable environment that reduces stress and promotes active behavior.

Fish coloration isn’t just a matter of genetics—it’s also influenced by their environment. Lighting plays a crucial role in how color is perceived, both by the human eye and by the fish themselves. The right spectrum can:
Make reds, oranges, and blues appear more vivid
Enhance iridescence and metallic hues
Help fish feel secure in their environment, encouraging natural behavior
Poor lighting, on the other hand, can wash out colors and stress fish.
CTT ColorBoost vs. Fish Color Enhancing Models
Wattage: 9.8W to 58.8W
Design: Triangular profile with enhanced red and green spectrum
Tank Fit: 30–120 cm tanks
Best For: Heavily planted tanks with ornamental fish
Benefits:
Maximizes red and orange tones
Enhances contrast in foliage and fish
Supports both plant growth and color enhancement
Wattage Options: 18W to 54W
Design: Wide, ultra-slim housing (84–114 mm)
Tank Fit: 30–120 cm tanks
Best For: Fish-only freshwater aquariums
Benefits:
Boosts overall color vibrancy
Balanced output minimizes eye strain
Ideal for display tanks and show-quality fish
Color-enhancing LEDs use specific wavelengths to target pigments:
Red light (620–660 nm): Deepens reds and oranges in fish like discus, guppies, and bettas
Blue light (450–470 nm): Enhances iridescent scales and helps in low-light visibility
Green light (520–540 nm): Increases visual balance and plant contrast
Together, these create a natural yet vivid look that mimics riverbeds or tropical shallows.
Creating a Low-Stress Visual Environment
Fish perceive light differently than humans. Sudden changes, harsh lighting, or too much brightness can lead to hiding, aggression, or loss of appetite. CTT’s LED lights:
Provide soft, evenly distributed illumination
Avoid excessive glare
Support healthy circadian rhythms
Keep tank temperatures stable thanks to low heat output
This translates to more visible, active fish with better coloration.
Best Use Cases for These Lights
Community tanks: Tetras, mollies, barbs, gouramis
Show tanks: Discus, angelfish, bettas
Planted aquariums with ornamental fish
Retail and display tanks looking to attract customer attention
These lights work well as primary or supplemental lighting in any of the above setups.
Installation Tips
Position: Mount over the center of the tank to ensure full coverage
Timer: Run lights 8–10 hours daily for natural cycles
Pair with feeding & water changes for ideal coloration results
Avoid mixing with overly cool-white LEDs which can mute fish color
Final Thoughts
