My p. socolofi has become really lethargic and will either lay on the bottom or swim at the top of the tank in the current. It's tail fin is no longer splayed out with all it's fin laying flat and the fish has just about stopped eating. If I don't tap on the glass it won't come to the feeding ring. All my other fish are perfect and my ammonia is 0 and nitrites are 0. My nitrates are now 40 because it's coming time for a water change. I have 2 rena xp3's running on the tank (it's a 30 gallon).
