I have a Dalmation Molly that has suddenly started swimming almost vertically (seeming to have a hard time keeping belly down). As long as it is at the top of the tank it seems to be able to keep its tail down but as soon as it starts to swim down towards the bottom of the tank its tail starts to raise up so the fish is vertical and it almost seems like it is going to turn belly up. The following is information about my tank.
