Our poor fish Rock N Roll has been having so many issues already...and now this. I was doing a 100% water change in his QT tank and had hip cupped and sitting on the counter next to the tank. I finished adding the water conditioner, looked down, and the cup was EMPTY! I panicked for a moment, then saw him lying on the counter - he has never been one to jump, but apparently he decided to today. I tried to gently scoop him up in my hands, but he flopped away from me. On the second try, I managed to get him and put him back in the cup. He lay still on the bottom for what seemed like forever, but was probably actually around 30 seconds, then started opening and closing his mouth and moving his tail a little. I lowered the cup back into the tank (now full of fresh, conditioned water) and he began swimming around and even ate a little. Initially he wasn't using his side fins much, but now he seems to be.
I turned out the light above his tank and covered part of it with a towel (leaving plenty of room for air to get in) so he can chill out a little if he wants to. I had already put a double dose of Stress Coat in the water so I don't think I should put any more. Anything else I should do? I'm a little worried about his exposure to whatever may have been on the counter - it was cleaned earlier this week with who-knows-what and there were a few grains of either table salt or sugar sitting in that general area where he was (whether or not he actually came into contact with these, I have no idea).
This is the last thing this poor guy needed..
