How to make CRS with better color?

Wednesday, 01 July 2009 12:18

This question is often hear in forum.

Long term external factors have great influence on CRS color beside the phenotype genes of a CRS:

Water temperature, ideally is 23°C, this gives the best color vs other factor like growth rate. 24°C to 25°C will work as well, but 26°C and above is not so much for color.
Light, there are 2 factors to consider, that is the invisible light and the visible light. A light temperature like in range of 10,000k will give better coloration for our eyes. And for invisible light, they will need those has UVB. I like to use 2 combo from Sera light tube, the 12,000K Blue Sky and Sera Terra FL tube (full spectrum daylight with 30% UV-A and 4% UV-B).
Food, plant based food like Mosura CRS Specialty food. "Meat" based food is better for growth rate while plant based food is better for coloration.
Water pH, keep at round 6.5 to 6.8. Lower pH will give not so nice color.
Water GH, around 6 to 8. Use Mosura Mineral Plus to increase mineral contents and GH.
Less water change and change lesser amount of water.
And of course good filtration of water, use canister filter and quality filter medium
