Hi! This was sold to me as a pea puffer, and I have it with my other pea puffers, and he is very friendly towards them, but he does not look like the others at all. He is about an inch long, he has blue eyes, but they tend to change color depending on the angle you see him from, he tends to stay near the bottom of the tank for the most part, and he also appears to have 2 very small horns growing on his forehead. If you need more pictures or more information please ask!
