I had put two large pieces of driftwood in the tank about 1 month ago which started to smell a lot I noticed today. So I pulled them out of the tank also today. So there is at least 4 days of the paros acting/swimming funny (2 of the 3 paros). Is it possible that the leaves and the wood affected the O2 level which then could affect the swim bladder of the fish? The fish uses every bit of energy it has to move around, tail dragging practically or swimming almost in a vertical position. Still eating, but I see no sign of improvement yet, it just sits on the bottom of the tank halfway on its side. No visible sign of illness, though the fish is much darker than the one which is acting normal.
