Help I Have a Green Mandarin in trouble!!!

Best of luck, enjoy your other forum. I hope your Mandarin continues to do well and I'm glad what you did worked for him.

Just one tiny side comment though. Do you have a CUC in your display tank? If so, a Mandarin dead in the tank wouldn't last long enough to cause damage to anything else..... max sized they aren't very large. Hermits/Snails/Urchins/Shrimp/Crabs/Starfish(Serpents/Brittles/Reg) would all make very quick work of it. But yeah, best of luck bud. Hope your tank continues to thrive :)
