Can someone tell me why my skunk cory is so discolored and why he is breathing so fast? My temperature is at 76 and has not moved for weeks and I just did a big water change of 60% yesterday. I thought my skunk looked normal until I started searching for pictures of other skunk cory's. Why is mine not white? Why is his stripe not clear at all? Why is he breathing so heavy? Also, I have 2 axelrodi and 1 orange laser cory in the tank and they are breathing very fast too. Really confused here :/
My pH is 7.6 from the tap. I've read that they will be fine with a wide range of pH though so that shouldnt be a problem. I have not measured ammonia, nitrite, nitrate because after doing 50-60% water changes every week this should be very low. My plants in the tank are java fern, water sprite, hornwort, anubias barteri, anubias nana, and 2 plants I'm not sure of. I'm using eco-complete and black sand on top of that. I am dosing flourish, excel, and NPK daily. My filter is an Aqua Clear.
