Hi! So, i am not completely new at the whole fish thing. i had a few goldfish for a few months before they died of ick and one being sucked into the filter because he was so small. beginner failures? so i am getting a 10 gallon tank soon. i dont know the filter i will get yet but it will have a bubbly oxygen machine contraption. (sorry im extremely tired atm xD) i am looking for some tank mates for a 10 gallon tank. i would like a type of catfish, and ive heard about the otos. are they active swimmers as well? anything you know about them will benefit me! so i would like a nice list of options as i am extremely picky. also, anything needed to put into the tank as well, like plants and little "decoration" things would be good too. Thank you!
