Ok i have a 30gal and i want to get a Mandarin and i would like some info on them like how to take care of them and how long i should have my tank set up before getting one?
You would not have the amount of LR to sustain the number of pods you would need to feed a mandarin.
Most recommend at least a 6 mo old tank, 125 lbs. of LR and a fuge for more pods to reproduce.
Most will not accept prepared food.
