Help me choose some lighting for my shrimp tank rack. There will be 9 tanks in total (standard 10 gallon in size), with 3 tanks on each level of the rack. I want to use 1 light above each set of tanks (so 3 lights total, or 6 if you suggest two smaller lights per level). I would like to put the tanks end to end so that equals about 66" across with some space between.
The tanks will only have low light moss type of plants, nothing special. The main objective is breeding.
Specific suggestions would be great
