Hi guys I posted a post about how my apistogramma agassizii double red "passed away" (https://apistogramma.com/forum/threads/apistogramma-male-death.23414/#post-109036) turns out he is alive and not doing well. I have no idea what to do from here. It appears he is blind. Pleas let me know what to do. I will be doing a water change and adding melafix. Any recommendations would be very appreciated (temp, medicine) thanks guys!
