Blue Manderins..

I have gradually put my reef style system together over the last few months. I have had a male blue manderin for about a month, two days ago I purchased a female. At first they seemed to get along well. But toward the end of the first day the male began bullying, even apears to bite her, although she does not apear to have any torn fins or other injuries.

What should I do? Will they get over there relationship difficulties?

I'm thinking of putting a small mirror (with smooth edges) in the tank to remind him of how males look & to give her some time out from his harasment.

How big is the tank?
How did you sex the fish?
That does not seem to be mating behavior. You can see that here on YouTube.

I'm not insinuating here that you haven't done your research, but I have to ask - Do you have the proper environment to care for 2 mandarins? I hate to be this guy, and don't take offense. This is a very demanding fish. It took me over a year to have a pod population heavy enough to maintain 1 in a 110g tank with a fuge. You don't state what size tank you have or how much rock, but you'll need a very mature tank to keep these fish. Most of them starve after 3-4 months unless they are eating frozen foods - a rarity.

With that aside, if you accidentally have two of the same sex they may fight. If they go past the "courting" stage and start "mating", they'll swim together locked up toward the top of the tank. It happens fast but they will do it quite frequently if they are mating.

Your bigger concern, again, is the food supply.

200 liters = 52.8344105 US gallons <--- google

Thats probably pushing it for just one mandarin. If you have two they will definitely starve eventually. They may be fighting for space. You should find the second one a new home and keep a really close eye on the first one.
