Welcome to MFK!
Your FH is still too young to sex...however, I’ve had 2-3 inch fry pair up and mated successfully. If you have any other FHs, their interactions can help in sexing and a clear shot of the vent will definitely help.
You’d get more help from me and others if pics were focused on the fish. I prefer a pic similar to the one I circled but zoom in and focus on the vent...if possible.
It looks like a male that big chin is very muscular showing that it’s a male 100^%Can anyone sex my fh? I feel like he’s male but the protruding tube under the belly makes me curious. About 4.5 inches long
