Hi Michelle, yes I got your email and we are going to work on a fuge this weekend. thanks alot it was very helpful. Roguecorps, that zooplanktos really looks like it may help the mandarin and buy me some time to get this fuge going and copepods.I have 2 units set aside that I am going to pickup sat. well I am leaning. from now on I will not buy one fish until I check their requirements first. I saw this mandarin in the lfs and wow next thing I know we are heading home me and my happy mandarin. he still looks really colorful and cruises around the tank I have been using a product called coral frenzy the ultimate coral food it says it contains oyster larve, salmon roe,krill,copepods and some other stuff thats supposed to be good so maybe this stuff is also keeping the mandarin happy and healthy.its kinda weird when I mix this stuff up and add it to the tank my open brain coral really opens up fast so they must like it. Thank you guys for all the advice this forum is worth its weight in gold. take care and have a wonderful weekend..:hallo:
