They are awesome! The cories are so entertaining to watch as they dart around the tank and turn over the substrates.
Our pleco is also of the "normal" variety, haha! He's already doubled in size since we got him (or her, who knows), and we're starting to get concerned about the safety of the tetras. He's killed one of them and left another with one eye, and we think he'll be much happier in the 55 once we get that set up. I am very excited to see how big he's going to get! It's definitely won't be comparable to a river catfish, but he'll be WAY bigger than any other fish we own! Though... my husband is also itching to get some oscars as well! or perhaps angelfish. We shall see.
We currently have 3 tanks! The third is a 10 gal divided in half that houses two bettas. It's... a lot. Especially with three BPs.. and two leo geckos.. and two large dogs.. all in a one bedroom apartment.Oh well. We'll be moving into a house in about a month, so that'l be nice!
