sorry to say, Flower sint lying burrito. Your madarin may live longer than this weekend, but unless you can get large enough source of food in your tank, (judging from the picture of it) itl prabably die pretty soon. If you cant get food or get it to a LFS, i guess thats that, but if you can i would bring your fish back, or go buy a bunch of pods. ( i know you've herd thiss many times but its the truth)
