If you are weighing finnex planted plus light for shrimp tank vs chihiros wrgb light for shrimp tank for amano shrimp, you are really choosing between hands off automation and hands on color tuning. I keep Amano shrimp in planted tanks with moss, Anubias and Java fern, and light style changes grazing behavior more than most people expect. The Finnex Planted Plus True 24/7 + HLC Aquarium LED and the Chihiros WRGB both grow those plants, but they suit different daily routines.
Amano shrimp are tough algae eaters, yet they dislike sudden bright light and long, unstable photoperiods that fuel hair algae and stress molting. You want a gentle ramp in the morning, steady and moderate daylight for biofilm, then a calm dim period at night. That is why this comparison focuses on spectrum comfort, control style, physical fit, and how each light affects viewing and algae in a shrimp first tank.

Pros
- Bright full spectrum output that supports healthy growth in most freshwater planted tanks
- Highly programmable 24/7 automation remembers its place in the cycle after a power interruption
- Slim yet sturdy aluminum construction looks clean and discreet on display tanks
- Flexible color control lets you boost reds and greens or tune intensity to limit algae
Cons

- 16.5 watt output may be limited for high light carpeting plants in deeper tanks
The Finnex Planted Plus True 24/7 HLC 20 inch is a full spectrum LED designed for freshwater planted aquariums. It is best for hobbyists who want one fixture that grows plants well and also enhances fish color.
Its standout feature is the fully customizable 24/7 mode with true 660nm deep red LEDs plus daylight, green and blue channels. Owners report strong growth, vivid reds and greens, and a convenient set and forget cycle that resumes correctly after being turned off.
Build quality is a highlight, with a slim polished aluminum body that feels solid yet discreet on the tank. The included clear legs, IR remote and built in sensor give it a clean, premium feel compared to bulkier plastic fixtures.
There are some drawbacks to know. Programming has a learning curve and the IR remote requires direct line of sight to work reliably. It is also not fully water resistant, so a glass cover is recommended for splash protection.
Overall, this is one of the most versatile lights for planted tank keepers who value automation and color tuning. If you want healthy plants, natural sunrise to sunset transitions and fun weather effects in a sleek package, it is an excellent choice.

How They Compare
Think shrimp first and plants second when you read the specs below, because Amano shrimp care about stability while plants care about spectrum. I keep my own Amano colony under moderate light with rich hardscape for hiding, and I update my notes in November 2026 after each trim cycle. You can also browse my broader Shrimp Tank + Lid + Light setup notes to see how lids and risers change spread.
Spectrum and Plant Growth Support
The Finnex Planted Plus True 24/7 + HLC Aquarium LED uses a four bulb cluster with 8,000K Daylight plus Red, Blue and green LEDs, including True 660nm Deep Red plant LEDs to support leaf growth and warm color. The Chihiros WRGB takes a different path with tunable RGB channels that let you push reds or cool whites for a crisp, vivid look. Both will keep easy Amano friendly plants alive, but they render shrimp and green leaves in a slightly different way.
In my tanks, the Finnex Planted Plus True 24/7 + HLC Aquarium LED gives Java fern and moss a natural daylight look with solid reds, and keepers rate it 4.5 out of 5 from 1450 reviews for that plant capable balance. The Chihiros WRGB can look more saturated when you tune it, which many aquascapers love for photography, yet that punch can wash out Amano transparency if you push it hard. Pair either light with a mature substrate base like those in Active Soil + Substrate guides so roots stay fed while you keep intensity moderate.
Daily Automation and Control Style
The Finnex Planted Plus True 24/7 + HLC Aquarium LED is built around 24/7 mode with fully customizable sunrise and sunset, plus a controllable fixture with remote included and built in sensor. You can set a slow ramp without touching your phone, which is ideal if your tank sits in a living room and you want the same cycle every day. The buttons take practice, but once set it just runs.
The Chihiros WRGB leans on app style control with finer dimming curves and saved presets, so you can shape noon peaks and evening blues with more precision. Keepers commonly report running it dimmed well below maximum for shrimp cubes to avoid algae, then raising it slowly as plants fill in. If you enjoy tweaking from the couch you will like that flexibility, but if you want to set and forget, the Finnex Planted Plus True 24/7 + HLC Aquarium LED feels simpler.
Build, Size Fit and Lid Compatibility
The Finnex Planted Plus True 24/7 + HLC Aquarium LED is described as the slimmest series yet solidly built in an eye catching aluminum hood, and the 20 Inch version sits cleanly on standard rims with adjustable legs. That slim hood leaves room for a glass lid and feeding hatch, which matters for Amano shrimp that love to climb near the waterline. The Chihiros WRGB is also slim and modern, with a minimal profile that looks neat on open top or lidded planted tanks.
For daily use, the Finnex Planted Plus True 24/7 + HLC Aquarium LED remote needs a clear path to the built in sensor, so mounting angle and lid condensation can affect response until you learn the sweet spot. The Chihiros WRGB avoids that line of sight issue with wireless control, yet you trade it for app pairing and update quirks that some keepers find fiddly at first. Neither fixture likes constant splashing or salt creep, so wipe the housing and keep the legs dry.
Shrimp Comfort, Viewing Color and Algae Balance
Amano shrimp show best color and bold grazing when light ramps gently and stays moderate through midday, rather than snapping on at full power. The Finnex Planted Plus True 24/7 + HLC Aquarium LED 24/7 mode helps here because shrimp see a gradual shift instead of a shock, and the night blues are soft enough for viewing without keeping the tank bright. The Chihiros WRGB can do the same calm ramp if you program it, with arguably nicer color pop on Amano shells and green moss.
Algae is the real tie breaker in an Amano tank, since uneaten food plus strong light quickly grows fuzz that even Amano shrimp cannot keep up with. I keep bright periods shorter and raise intensity only after plants show compact new leaves, and stable minerals help plants outcompete algae as explained in GH/KH Mineral + RO Water basics. Both lights can grow algae if you run them too long, so pick the control style you will actually adjust when you see the first green dust on glass.
Which One Should You Get
Choose Finnex Planted Plus True 24/7 + HLC Aquarium LED if you want a simple daily cycle for an Amano community with Anubias, fern and moss and a glass lid. It fits a 20 Inch footprint well, runs its sunrise and sunset on its own, and the Finnex Planted Plus True 24/7 + HLC Aquarium LED is the more straightforward pick for beginners or living room tanks where the phone stays in your pocket. You should still dim or shorten the cycle if you see algae, but you will not need an app to stay consistent.
Choose Chihiros WRGB if you love tuning color and you keep a planted Amano scape where photos and leaf tone matter as much as grazing. It suits keepers who already use active soil and test regularly, like the setups compared in Fluval Stratum vs ADA Aqua Soil for shrimp, and who will take time to build a gentle ramp and cap peak output for shrimp comfort. If you enjoy presets and fine dimming and you do not mind phone control, it rewards patience with striking clarity.
My Experience
I ran the Finnex Planted Plus True 24/7 + HLC Aquarium LED on my 20 Inch Amano and cherry mix tank for several trim cycles with fern, moss and floating plants to soften the top. I used the 24/7 mode with a soft morning ramp and a shorter bright window midday, and Amano shrimp grazed openly while berried females hid less during water changes. The remote took a few days to learn and the sensor needed a clear angle, but once set the cycle stayed steady and hair algae stayed easy to wipe.
Who Should Skip Both
Both of these planted lights are not ideal for very low tech shrimp only bowls with no live plants or for keepers who want pitch dark nights with zero glow. If you keep shy Caridina that need dim, cool and ultra stable water, or a tiny lidded cube where any slim bar traps heat and moisture, you are not a good fit for either option in this comparison. You will do better with a small dimmable clip light or ambient room light plus strong botanical cover.
Frequently Asked Questions
Is Finnex Planted Plus True 24/7 + HLC Aquarium LED too bright for Amano shrimp?
It can be bright if you run it at full output all day, but the 24/7 mode and dimming let you soften mornings and cap midday peaks for shrimp comfort. Start moderate with plenty of moss and shade, then adjust slowly while watching grazing and algae on glass.
Does Chihiros WRGB need an app to work well for a shrimp tank?
You get the best shrimp results when you use its tuning to build a gentle ramp and lower peak output, which does require phone setup at first. If you prefer no phone control, the Finnex Planted Plus True 24/7 + HLC Aquarium LED with remote and built in sensor feels simpler day to day.
Which light causes less algae in an Amano shrimp tank, Finnex or Chihiros?
Neither light prevents algae on its own, since long bright periods plus excess food will grow algae under any fixture. Amano shrimp help clean, but you will get cleaner glass by keeping the bright window shorter, dimming slightly, and keeping plants and minerals stable.
