Hey I have 2 Peacock Bass (about 10" and 8") a Frorida Gar and a Common Pleco in an 140gal aquarium. Ive had the Bass about 4 or 5 years now and recently the larger one hasn't been eating his pellets. Its like hes having trouble seeing them, he sometimes catches a glimpse of one and gulp at them but usually misses. Both Bass seem to have the slightest tinge of gray to their eyes but only the one is having trouble seeing. I had the water tested and everything seemed to test fine. I will get it tested again and post exact numbers. Any idea with whats going on in this tank?
