Recently, as I was doing a water change I set the siphon down in the tank for literally 5 seconds to set something down. I look back and my pearl gourami has swam into the siphon! I know it didn't suck her up because its not that powerful and she always follows it around when I clean the tank, so I'm not that surprised. After removing the gravel vac part from the hose and shaking it gently to loosen her up, she swam out the back. I thought she was fine at first until I noticed a bunch of scales in front of her dorsal fin had been torn off her back, with the white tissue underneath exposed. I finished the 50% water change, and now I am dosing with stressgaurd on top of my normal plant fertilizers. I really don't want her to get any worse, she is my favorite in the tank, what else can I do to prevent her from getting an infection? My water parameters are fine, is clean water + stressgaurd enough?
