Male xenotoca eiseni, you can tell by the slight indentation at the bottom of the anal fin.

 

[TallTree01]

That's a female fish because of its fat gut.

Well Dreamer asked for my hardest question, and that was about as hard as I could come up with in the timescale.
 
Ninjouzata is quite correct, that is indeed a male Xentoca Eiseni, common names include redtail splitfin and orangetail goodeid. If you click on the image to enlarge it, it's easier to see that the anal fin has a notch in it, making it look a little like a child's mitten. The "thumb" part of the mitten is called an andropodium, and performs a similar role to the gonopodium of a poecilid livebearer.
 
Ninjy, over to you.

That is one very overfed and undercolored male.

Unfortunately I cannot think of a question, so I pass it to the next person who posts

I am a small, saltwater fish with striking colors. I can be found in the Western Pacific waters near the Philippines. I am very difficult to keep in captivity and typically die of starvation at the hands of novice aquarists and am usually halfway starved at the LFS. Despite my small size, I require a minimum of 75 gallons with plenty of live rock and an abundance of live food. In home aquaria, I am constantly picking the live rock in search of a meal of copepods and can quickly decimate the population. Very rarely can a member of my species can be trained to accept frozen food. What are my common and scientific names?

 

[LILmollyBri]

lion fish  or that green goby 

 

[nikkifro8994]

Not a lion fish. Green goby? Specify please? I want the scientific name (genus and species) and one of the common names. I can think of 4 common names off the top of my head.

 

[nikkifro8994]

Any ideas?

 

[Ninjouzata]

The only thing that came to mind was the mandarin dragonet (Synchiropus Splendidus) but I don't know anything about SW fish

 

[nikkifro8994]

That's the one! Your turn.

 

[Ninjouzata]

Ahh I stink at coming up with Qs..here's an easy one then, what fish is this?

 (Not my picture)
 

 

[sawickib]

Just looks like a polypterus endlicheri, is it a sub-species of a lap? No just looks like a endi...
 
EDIT: Theres more endis and ornatipinnis in the back ground... And a peacock bass

 

[Fishmanic]
