Hello everyone. Everything with my 3 year old Oscar Big Boy has been going great!!! He looks good & swims around his tank which is a 125. The other day I cleaned the filter's & the next day I did a water change. Ever since I did this he hasn't been eating as much. I have done this before and he has been fine. Any idea's?
