So in my mini aquarium I've got some red cherries a ghost or two and an amano. unfortunately an amano I had earlier died recently . Before it died it's body slowly went from clear to white and it looked as if it was going through dementia. Usually they're not afraid of me but when it began its slow descent it would be scared by every little thing and would go through small bursts of energy to swim away. Eventually it became very grounded and wouldn't even stand straight. Soon enough he passed on and my other amano shrimp seems to show similar traits but not as exterme. All of the water conditions have remained the same, neutral ph about 71-73 deg F and no known toxins in the water. Any idea what's going on with the little guy?

Also, how have i not noticed these cooky icons?!
