So, as I said in my other thread, I got a fully-stocked 8-gallon hex tank from a neighbor who moved. One of the fish is a Common Pleco. I just found out through some online research that my Pleco will easily grow to 20 inches. I want to get a larger tank, but I've been told that my Pleco will require up to 125 gallons, which means that my fish tank would be relegated to the basement. I just scored a 30-gallon aquarium from a friend who's been in the hobby for years and is quite an expert. However, I've never had a tank larger than 10 gallons. Should I put my Pleco up for adoption or pull the trigger on a large tank?
