It's been 24 hours since they've been in the tank with two silver Dollars who are fineI got the tank and put water in it that I had purified and cleaned and took some water from my 55 and filled the 75 3/4 of the way. And placed both Severums I received. The Banded Severum is doing great, a little bruised from going nuts during the trip in my truck. But the Red Severum is tipping sideways now and breathing a lot slower. It moves occasionally like it's fine but will eventually fall to the bottom of the tank! I never had this happen and I even took the time to get the water ready well before the fish! A quarter of the water is from a cycled tank as well, maybe he's stressed or was damaged on the trip home
