Maximum Size: The Nemateleotris magnifica grows up to 3 inches.
General Size Specifications: These fish generally will come to you 1 - 3 inches.
Minimum Tank Size: The Firefish Goby prefers a tank of at least 20 gallons with plenty of places to hide & swim.
Diet: The Nemateleotris magnifica is a carnivore and typically likes to eat zooplankton, especially copepods and other crustacean larvae. Although you may need to offer live food when you first introduce the Firefish to the aquarium, it can become accustomed to eating small amounts of frozen foods, such as brine shrimp, and flake foods several times a day. They should readily eat almost anything you offer them.
Level of Care: The Firefish Goby is a low maintenance fish.
Behavior: The Firefish Goby may act peacefully toward other fish, but may fight with its own genus.
Hardiness: This is a hardy fish.
Breeding: Able to breed.
Water Conditions: Keep water quality high (SG 1.020 - 1.025, pH 8.1 - 8.4, Temp. 72 - 78° F).
Range: Indo-Pacific.
General Notes: The Firefish goby is slightly timid but will become bolder with time. Likes plenty of places to hide and is suitable for most reef settings. Will fight with it's own genus and tends to jump. Best if kept alone or in pairs to keep fighting to a minimum.

Yes Firefish no mandarin, although thats how one would sex a mandarin too. Here are some pics of firefish pairs in the wild. I have read that females tend to be thinner than males too.

Those fish look identical to me. Which one is which?

In the first picture the difference between the two can be seen (to me anyways) in the size of the longer dorsal spine in the left firefish. The only thing that comes to mind for me, is that maybe not ALL pairs look like those pictured above. I'm sure that dorsal spine length varies from specimen to specimen, especially in the wild. For me, the second picture displays no significant difference between the two firefish.
Then again if you're able to catch the firefish in the act of laying eggs, then you know it is a female.

I hear as juveniles they are A O.K to have together in a closed system, however when they mature they begin to pair off and such

You'll have to keep us updated on how they do together long term. I've always heard they don't work out in multiples in most tanks. If you did get a bonded pair, that'd be pretty sweet. I don't recall ever reading that they can be distinguished between genders.
