LOL He's still hanging on ;) He didn't eat for a couple of days, but he's swimming around a lot more, and actually sleeping in the rock and sand now occassionally.
I did make a couple of mistakes....during one of the water changes, I forgot to add more rodi to the new saltwater, and it raised the salinity in the qt to 1.013 or so, up from 1.009...but he seemed ok. Then yesterday, I did an even bigger mistake of not checking my salt water and I realized the heater I put in there to warm it up had food stuck to it :( And it stayed behind, causing the ammonia to go up...and when I made the water change, my qt's ammonia level went up! Now I have nitrites and ammonia :( . I'm preparing more clean saltwater now, so I'll do another massive change later today. He seems ok though...not eating again, but it's probably cuz of the ammonia/nitrites.
Good news is, since he's swimming more, I can see him better....no white spots!
