my names is Marc I have a 4.5ftx5.5ftx5ft pond, It contains Koi and Tench. New to th site but previously studied Aquatics and Ornamental fish at college.
Hey Marc, welcome aboard! What was the name of the course on ornamental fish and where was it at? I took a bunch of bio in college, but I don't remember anything that specific, but that was a long time ago...
