I gave this midas to a friend who had a ready 75g when he was 7", he was crowded in my 55. Now he has that tank to himself, and is eagerly awaiting another upgrade! This common pleco was one of my first fish 11 years ago, reached 14", died a few months ago. Little did I know how big he would be, I ignorantly bought him for a 20 gallon, my first tank as a teen.
