Copepods and amphipods will spread rapidly and naturally. Systems with Mandarins have very high demand on these populations, and generally require deep sand bed systems and a refugium.
Commercially packaged copepods are available at your LFS, for supplemental feedings. Generally speaking, you will need a minimum of 75 to 125 gallons of water per Mandarin, even in systems which utilize all of the methods discussed here.
Ok i have a 40 gallon with 40 lb of live rock and a 3 inch bedof crushed coral. Ive had him for bout a month or so. And he has done realy good. but the past couple of days ive noticed he has started to get skiny. What else can you feed them. And how long do the live for?
