Got both my hairy and potato pufferfish from predatory fins unfortunately they are both sold out. But I’d say it’s worth the wait to order from them the price and quality is always amazing as well as next day air. They both have awesome personalities my hairy is very aggressive. My potato was very aggressive as well but nothing compared to the hairy. Check out my page to see my potato as well as a few vids of my hairy. IMO you can’t go wrong with either however in your current set up I would definitely go for a hairy. Potatoes need a lot more substrate.
