They are 2-2.75in. I just got them saturday. I been feeding them beefheart in the morning and chickheart at night. I need to get some shrimp and krill. I'm impressed with these guys, they are not skittish like the caribe I had at the same size. And they have the same ferocity in eating like the caribe but don't have the appetite. My caribe at the same size would eat double what I feed the pirayas. I'm completely satisfied.
Thanks for the complements guys
