i have come across an interesting deal with a friend but i need help on priceing these fish because i know nothing about them. First there are five red pellied piranhas and they range in the length from about 4 to 5 and half inches and all are in good health as far as i know, he wants to sell me these five piranhas for 50 dollars for all five and it sounds like a good deal to me but i want to buy them then take them to my LFS for store credit and thats where my problem comes into play i dont know how much i should ask for all five, and i dont want to get ripped off. SO anyone plz help me on how much i should ask for these fish. Also i live in COlorado if that makes a diffrent because i know there illegal in some states. THANX
