I recently bought a paradise gourami (female) at petco a couple weeks ago. I had her in a 8ish gallon tank and moved her into a 20 gallon tank yesterday. She won’t eat food, she will spit it out, and i’ve noticed these spots on her side. Could it be a parasite? Or just scales. Other than not eating and having three spots on her side she seems perfectly fine, she still swims fast and is very energetic. Please help!!
