Hey everyone! Sorry for such a late response, kinda just made the post then forgot about it haha. I have a 20 Standard, not long. There are definitely some awesome fish that was stated in the discussion! I'm my personal opinion, I like the pea puffers a lot, I think they're pretty cool and I would love to get a few of those guys, especially if they have a strong personality. It's going to be a display tank in my office so I'm thinking about getting it completely planted as well. With their aggression, I'm thinking I can fit about 5 in the tank? My local aquarium has like 15 in a 10-gallon display tank and they seemed to do fine, not too sure about the statistics of it though. Similarly, what can they be paired with? I'd like to have a robust tank with a few other fish here and there to utilize the entire scape, low, middle, and high.
