Has this ever happened to anyone? I put all my fish and inverts from my 55 gallon into smaller tanks as I was setting up my 75 Gallons. After a while I noticed an amano shrimp turned upsidedown and I thought it died because of shock, but when I looked closer it was still moving its legs a little. After a couple more minutes it turned bright blue. I got my 75 gallon all setup, and I put all the fish back in and also the shrimp because it was still moving its legs but still upsidedown. In the morning he is back grazing all the algae and back to it's normal color. Any idea what happened?
