This article reviews the Finnex Ray2 and MonsterRay aquarium lights, comparing their performance in a 30-gallon planted tank. The author upgraded from a weak, inadequate reef light, seeking better plant growth and enhanced fish coloration. Their previous positive experiences with Finnex products influenced the choice of these two specific models. The setup involved two 30-inch Finnex Ray2 bars (7000k) as the primary lighting source, supplemented by a Finnex MonsterRay to boost fish color vibrancy.This comparative analysis explores the effectiveness of each light individually and in combination. It examines their impact on plant health, fish coloration, heat output, and overall aesthetic appeal. The author meticulously documents their observations after a week of use, detailing both the benefits and drawbacks of each light. The ultimate goal is to determine whether this dual-light system represents a worthwhile upgrade for planted tank enthusiasts seeking optimal plant growth and vibrant fish displays.
Pros And Cons
- Enhances fish colors
- Subtle effect, not overly bright or unnatural
- Generates significant heat
- May not be sufficient for plant growth on its own
- Creates a shimmer effect on the tank (may be undesirable for some)
- Produces less heat than Monster Ray
- Good for plant growth when used with other lights

The Setup: A Craigslist Score
I recently acquired a 30-gallon tropical community tank, complete with canopy, stand, and a rather underwhelming reef light, all for a steal at $75 on Craigslist. The previous owner had used it for a saltwater setup, densely packed with coral – a setup that ultimately failed due to a lack of experience, resulting in the loss of the entire coral and fish population. This unfortunate event led to the tank's incredibly low price.
The reef light, while functional, cast a harsh, white light that washed out the colors of both the plants and fish. This spurred me to upgrade the lighting system.
The Lighting Upgrade: Finnex Ray2 and MonsterRay
To address the inadequate lighting, I opted for two 30-inch Finnex Ray2 bars with the popular dual 7000k option. I also added a Finnex MonsterRay, a supplemental light intended to enhance the colors of my fish. My previous experience with Finnex lights on my nano tanks was overwhelmingly positive, driving my decision to use them again.
The Ray2 lights provided a significant improvement in plant growth, and I was eager to assess the MonsterRay's impact on the fish's coloration. I expected subtle enhancement rather than a dramatic transformation.
Performance and Color Enhancement
The MonsterRay, while not a major contributor to plant growth, undeniably improved the colors of my fish. My Rams and Neons exhibited significantly richer coloration, and even the cherry shrimp showed a notable difference. The light is subtle, enhancing rather than overpowering the natural hues.
A comparison with the lights off and on clearly demonstrates the MonsterRay's effect on color vibrancy. The reds, purples, and yellows of my fish became much more apparent with the MonsterRay activated.
MonsterRay as a Standalone Light: A Cautionary Note
I tested the MonsterRay as a standalone light source and found it inadequate for plant growth, even though it looked brighter on camera than it was in person. The tank was noticeably darker, with insufficient light for healthy plant growth.
I strongly advise against using the MonsterRay alone. It should be used to supplement a primary lighting system, like the Ray2, to maximize its color-enhancing benefits while still providing sufficient light for your plants. A timer could be used for an hour before and after the main lights for a sunrise/sunset effect.
Heat Output and Additional Thoughts
The MonsterRay produced significantly more heat than the Ray2s. While not dangerously hot, the difference was noticeable. I'm concerned about the potential impact on the light's lifespan. The Ray2s run considerably cooler.
After a week of use, plant growth remained consistent with the previous fluorescent lighting. I'm considering adding another Ray2, possibly a 10000k option, to add more blue light and reduce the yellowish cast from the existing lights. The added blue greatly enhances the colors of the neon tetras in my other tanks.
Conclusion: A Winning Combination
The Finnex Ray2 lights provide excellent plant growth, while the MonsterRay significantly enhances fish coloration. Using the MonsterRay as a supplemental light is ideal; using it alone is not recommended. While the MonsterRay produces considerable heat, its impact on color is undeniable. I would definitely recommend both lights together for a vibrant planted tank.
The shimmer effect created by the combination of lights and strong currents is a matter of personal preference. Some may find it distracting, while others (like myself) find it visually appealing. Overall, the upgrade significantly improved the aesthetics and health of my planted tank.
