the pink looks male. Hard to tell on the smaller striped one yet. If its a female the belly will go orange soon. good luck.
The fish may tell you by their behaviours in the tank. they will pair up soon if they are male and female.
IPU,PJ pets, both in RICH.
Your Pink con is not a true albino, there's no such thing as an albino con(not that I've heard or seen).
It's actually a strain called Leucism or a Leucistic.
*Leucism is a condition characterized by reduced pigmentation in animals and humans. Unlike albinism, it is caused by a reduction in all types of skin pigment, not just melanin.
I see a slight pink hue near the belly & tail of your pink con, so I'm not ruling out it being a female.
I can't guarantee it though because it's a blurry pic.
I found the member selling that tank you were interested in.
