Hi guys, I don't know if you guys will believe this but, I have two mandarins in a 20gals and a 5gals that are eating mysis shrimp. The green mandarin in the 20gals has lived for 7 months now and seems to be pretty healthy, he grew quite a bit since I bought him. The spotted mandarin in my five gals which I just bought for a couple of weeks is also eating mysis shrimp. Here is how I did it, use a turkey blaster, target feed brine shrimps then starve the mandarin for a day and super target feed the mandarin with mysis. I could see that his belly gets fat after he ate the mysis shrimps. Anyways, my question is that will mysis shrimp provides enought nutriention for my two mandarin to exceed their nutural life span? Or do I have to ween my mandarins to something else?
