Environmental DNA Detects Invasive Species in Gatineau Park Lakes

Aquarium Help

Hey guys! First time posting on here. I’ve never had any fish tanks before, but I’m excited to start learning the hobby :). I got a 20 gallon tank and recently put a Discus in it. I know it’s a little small, but my local fish store is very knowledgeable about this kind of stuff. The discus is swimming a little weird, and I might be paranoid, but could it be the ammonia levels?
I KNOW they’re really high, but the fish store said that the ammonia will go away after the fish is in there for a little bit. Do I need to move to a bigger tank?

Besides the point, but I’m having a lot of fun in the hobby so far. My Discus might be my favorite fish that I’ve ever seen! She is just so beautiful.
