Good things sometimes happen unexpected – alas, it was a nice surprise when Hillary E. from http://rah-bop.com contacted me and sent me an awesome drawing showing the caridina cantonensis color variations. This shrimp species is the most fascinating one, with still many secrets and information to be revealed.

Although I have left my old home in March already, I have not able to reset my tanks yet. Still my free time is so limited that I need the week ends to relax and for my family and relatives. However, I have done some research on LED aquarium lights, as I want to keep my electricity bill low.
The main question with LED lights is:
- Which color temperature (Kelvin) should it have?
- How much lumen / wattage do you need?
- What are you able to spend?
Asking my shrimp keeper friends, I received this product advises:
- Warm White 2.700K
- Neutral White 5.000K
- Ultra White 7.000K
- Ultra Blue White 15.000K + Peak 465nm
- Ultra Blue Red White 15.000K + Peak 465nm + Peak 650nm
- Nautic Blue 476nm + Peak 465nm
With the option to chose individual configurations and adapters, it highly can be specified to your needs. However, you have to invest some bucks in it (155€ a 60 cm light bar without adapter). My favorite shop to buy would be Krüger Aquaristik.
The KR series aquarium lights (KR90) has not been mentioned by any of my buddies, and looks a bit massive for smaller tanks.
As my funds are limited at the moment, I probably will go for an LED Intenso light bar with 15.8W /6500K/792 lumen if I decide against a planted tank (moss only tank). The price is ~56€ on ebay plus shipping. However, I still need to calculate how much light I’ll need for the water plants in my RECTA 50x30x30 white-glass tank.
