i dont know thats what was said to my buddy tho when he ordered either way if it is a F2 or not i love the cubans they are nice looking fish. I have it in my 29 gallon grow out tank right now cuz it is only 1.5 to 2 in it is gonna end up in my 125 gallon with a Venny pike a Female loisellei and a 5 spot jewel cichld. I am trying to find something else to go with the cuban to grow with but i dont know what can go into the 29 with it for now so they grow together and then go into the 125
