i have a 7 inch tiger shovel nose and recently he has a little bubble forming under his mouth. i noticed it last night and it wasn't there 3 days ago. all the specs in the tank are great. no ammonia. no nitrate or nitrite. ph is around 7.4. i have a 140gallon aquarium. no plants. its very clear. wondering what is causing this? i intruded a talopia yesterday so maybe that? any help would be great. he acts normal. eats normal
