HI all! I’m a noob here but 20+ years experience fishkeeping both fresh and saltwater. I’m super excited about this little one I recently acquired, this morning after he had a little constitutional I happened to catch site of this and wondered if I’m looking at a nice triangular boy vent or just another scale on the analfin combined with wishful thinking lol! Was hoping for some second opinions. How I got that shot against a tiny bit of black in the background I’ll never know Thanks in advance!
