My yellow watchmen goby has been breathing hard the past couple of days, all my other fish are doing fine. Ammonia 0, nitrites 0, nitrates around 10, phosphates 0. Tank is 4 months old, finished cycle about 3 months ago (fishless cycle). His bottom lip also seem odd. Not sure what’s going on. (Don’t mind all the floaties I had just fed the tank, o my time he comes out, and my clowns photo bomb haha)
