alright at the moment he doesnt have any for sale but he said to forward his email in order to give some tips on training them
"Hi Louis, at this point i have 4 mandarins (2) female spotted and one male red/green & one female red/green, all medium sized eatting blood worms, spirtula mystis shrimps, bone meal and marine cuisine and i'm attached to all of them, what i can suggest is to tell the people you know who are interested in getting their mandarins to eat regular food, is to buy live brine shrimp that some pet stores sell, tell them to turn off their air flow and feed the live shrimp twice a day and to be patient, i would say give it like 3 or 4 days and then start to give them frozen shrimp and see if they're trained, if that worked, then introduce the blood worms and a few days later, the bone meal and marine cuisine, of course theres no guarantee it will work but its worked for me, alot depends on where you buy the mandarins from?, always good to make the petstore *feed them just to make sue they're eatting anything, the one store i have no luck with is Pets Warehouse, their mandarins 'die' on me after '2' weeks, in Queens, i like Fishtown and or Coral Aquarium, Drs Foster & Smith are good and guarantee two weeks! If i should change my mind and decide to sell i'll email you but for now, i've been lucky to have them over two years, as you know, fish need the same exact boring enviroment every day to feel safe and then they celebrate birthdays, i have not been able to find the blue/green med. sized female mandarin lately, so i have my eye out for one, another secret is, i keep my mandarins seperate from other fish and in a small 2.5 tank with only mandarins so no one else eats their food! Walmart or Petland, sometimes Craigslist has decent prices on the 2.5 kit or 5 gal, even Pets Warehouse (just don't buy their mandarins for training on regular food), acrylic is fine, you can mix 2 females or a male & female but 2 males together spells war, you can pass my email on, hope it helps

I have not done any of the practices so i cant guarentee they'll work and I'm not up for the discussion on ethics of keep mandarin in small tanks....he has obviously had a lot of success with them and knows more than we do since he trains them pretty often....there was a point where he would email me about new mandarin he had up for sale pretty often but it seems like he has settled down a bit with training and selling
