Got hit by a power outage. My tank went 60 hours without heat or filtration. Luckily, no casualties- all my fish seem FINE, except my arowana. Both his eyes are now super murky/cloudy, and his body looks like there is dead skin coming off of it. Other than that, hes swimming normally and seems to be finne. Has anyone experienced an Arowana recovering from this before? Are his eyes going to clear up eventually?
