Looks male to me but this one's a juvenile. Its a red dragon. Some red dragons grow koks at around 3inches or so with proper care. But lately more red dragon hybrids have great genes whre their nuchal hump starts growing at the size 1+inch . Put him in a smaller space where you can let his personality grow and make him pop our more. Put a divider or something to less down the space because they tend to be skittish in a bigger area. Make him more active
