I will second this as they are Longnosed and these are not easy fish to raise if you are not already prepared to do so or have much experience in raising gar from fry.
Here is what you can expect:
You have eight now...one will eat all the others then you will have one that you can work with at a better size. Usually around 3 or 4 inches. from here they are easier to feed but will likely mangle themselves by smacking the glass of the tank if you are not careful. Keep them in nothing larger than a 5 gallon until the fish reaches at least the above 3 to 4 inches and then step the tank size very slowly. DO NOT put these fish with other fish.
Good luck
