my aros a few months old and ive never had problems til now, 1st he stopped eating for a few weeks and now he started swimming between vertical and normal, hes seems to be fighting it, and for the majority of the time hes swimming the right way but after about 20mins hel go vertical again and quickly fix himself. i really hope its not too late to save him, i just did a 40% water change and was about to clean the filter. is there anything els i could do? i checked the ammonia level and that was fine , but the Ph is a little high even after the water change. what els can i do?
