I have to check the name of them. They were the fancier fatter ones with the bigger fins. Some were plain orange and some white and orange.
I think that tank is around 10 gallons with the pump and filter and stuff it came with.
I will find out in more detail and get back to you.
They sound like fan tails. How many do you plan on keeping? You should at least keep 2 because they are social. To support them as adults you should get a 30 gallon tank. I suggest getting an emperor 400 bio wheel. Thats what I have on my 30 gallon tank with a ryukin and a black moor.
