Ok, so this is what I have been reading. I've been doing plenty of research to make sure I know everything before I start to freak out. Mandarin's lose color when they sleep and look near dead as well. It's possible when I was looking at him he was just extremely stressed and that could be why he has lost some of his color. His dorsal fin is laying against his body and his other fins are also closed up which is really leading me to believe he's just stressed from the move right now. As I mentioned before he's currently in the fuge so food is available for him. I don't know what exactly they are supposed to look like when they are "fat" and I don't know if the fish is truly skinny at the moment. The area where the propeller type fins and his pectoral fins meet is where it looks like it might be a bit thin. I can't see any other type of "thinness" in the body aside from the area I mentioned. Last night I took a look at him when the lights on the fuge came on (around 1 in the morning) and he was moving around still low against the ground (I believe they stay against the sand bed for the most part, correct me if I'm wrong) but making an attempt to eat some of the copepods along the glass and along the sand bed. With that being said... MANY of them made their way towards the mid area of the tank and the Mandarin didn't care to go that high up to get them off the glass... do I have to push them down for him or do healthy mandarin's typically eat from top to bottom side to side (no offlimits area)?
Also, I don't have any type of cover for my fuge... are mandarin's known to jump? If they are I will be getting a top on my way home from the office today.
Lastly, I didn't at all think of seeding my DT. Thank you for the idea and I'll be working on that today as well. Any suggestions beyond that?
Thanks all for the comments again!
