I have a dozen or more from 3.5 in he's all the way to 7ish inches, what should I price the group at most are around 4 to 5 inches
500 is the low end of what they really are worth as a group of 12 plus individuals. Nothing less than 500 for the entire group its already a steal at 41 apeice for 4-5 inchers with some 7 inch loaches based off 12 pieces.
My LFS sells 3 inches at 25 bucks and 4-5 inchers sell like hotcakes for 50-75 a piece at that LFS. No sellers sit long on bigger loaches.
Dont price them at 400 because you will get flippers profitting off your hard work.
