I was thinking about getting a mandarin goby and i was wondering if one of them ate frozen brine so i wouldn't need to buy copepods. And how much live rock do u need to raise the copepods and i heard that grow on the sand would the mandarins eat that.

Mandarins can be trained to eat frozen, but will not live long from it, especially not from brine. That is like only feeding your kids cotton candy. They absolutely MUST have pods to eat. Unless you have at least 70-100lbs of very mature live rock, and a refugium that is set to breed copepods, please do not buy a mandarin. Mandarins can eat hundreds of copepods per day.

I have to disagree. My mandarin ate frozen foods and did not pick at the rock at all. He swam in the water column with the other fish and lived for 7-8 years.
He ate a nice varied diet... whatever the rest of the fish were eating.

i feed it mysis shrimp.

As long as it's well fed and happy, you "should" be fine. More and more mandarins are accepting frozen food. Years ago it was rare, it's still rare now, but not to the same extent. The ideas about what mandarins will accept as food is also starting to shift.
The thing is, many people go "Oh, my mandarin eats frozen food, he doesn't need pods." This is where people get into trouble. Then all they do is feed frozen brine which is like giving a kid nothing but candy and the mandarin becomes malnourished. The pods should be in their diet regardless, unless they absolutely refuse them (which is highly unlikely, but can happen). The other issue is, they eat all the time, so the pods need to be available all the time, not just when you feed your fish morning and/or night.
My suggestion would be to still seed your tank with copepods at least once a month, if not twice, even if the mandarin accepts other forms of food and to add vitamins to any food that is added to the tank for him to eat other than pods. This will help increase his chance of survival. My mandarin is slowly starting to accept other forms of live food like baby brine and mysis and will occasionally eat frozen food added to the tank for other fish. I still seed my tank, it's a 155G with over 200lbs of rock, plenty of pods, and I still seed. As they get bigger, they want more food. Mandarins have the metabolism of a teenage boy running a marathon, tons of pods can be depleted in under a week.
On a side note, pods are good, they'll sift your sand a little and some eat detritus, so you really want them in your tank regardless, so seed it.

Agreed, I waited 2 years before getting mine 75 with a 55 sump/ref

I'm not saying pods aren't important.... they are for every pod eating fish. But a mandarin that takes a well rounded diet does not HAVE to have them in order to live.... and live well. That's the only point I'm trying to make. The problem, I believe, is in people's evaluation of how well they are taking frozen. They need to take it with gusto, take more than one food item and be able to compete with whatever else resides in the tank. If they fall short on even one of these, I believe they will fail to thrive without the addition/presence of pods.

This whole topic is sure an "individual fish" thing. I'm changing my mind, a little, on these guys; but one thing I'm sure of. they should not be tried by beginners or kept in newly set-up tanks.

Definitely agreed. Also, if you really want one, do some research on what you're putting with it. A lot of people don't realize that other fish (especially SixLine Wrasses) also eat a lot of pods and the two will usually not coexist together.

Another bit of info that you don't hear much anymore: Anemones often eat Mandarins .
Yes, but let's clarify. Long tentacles and haitians are more likely than a bubble tip. I had a haitian eat one!
