My 3 dwarf puffers have been hiding for the last month among the thick plants. They used to come out to see me when I approached the tank, were curious about me, and very eager to eat. Now they appear terrified and only hide in small corners and only swim when trying to hide from me. They do not appear to have any disease as I can tell. Their colors look fine and they still have nice little bellies on them so I know they aren’t starving.
Addition Info: I’ve had my dwarf puffers for about 6 months. They are in a 10 Gallon tank with 2 Oto’s. The water chemistry is Ammonia 0, Nitrite 0, Nitrate 15, pH 7.2. I do 40% water change/siphon/clean filters once a week. Change filters every month. I feed them live black worms.
Why have they stopped being friendly and appear constantly stressed? have others had this same experience? Could it be the Oto's annoying them?
