That is a Needle Nose Gar
I Have one that is in freshwater setup and it thrives Perfectly in its tank
it is About 7 Inches Long And is in a 55g Tank w/Silver $'s, Tinfoil Barb, Bala Sharks, Crayfish, Iridesent Shark, Convicts, A Big Pleco, A Leopard Puffer, Bumble Bee Cats, A lot of cories, And 3 Dojo Loaches.
I'm Feeding Her 2 Different Types Of Feeder Fish:Feeder Guppies And These Slightly Bigger Types I Don't Know What They Are Called. I Also Have A Net Breeder In The Tank That is Holding 4 Female feeder Guppies And 1 Male Feeder Guppie So That I Don't Always Have To Go To The Store To Get Her Food.
Besides That She Is A Lovely Fish That Is Fun To Watch And Fun To Watch Eat.
