The damsel and the cardinal both died yesterday :-(
I can understand the cardinal -- he wasn't eating very much and he wasn't very active, even if that's normal for new cardinals, so it could be that he just wasn't going to make it in a new tank regardless, even though I'm sure there is more I could have done for him.
But the damsel? He was doing fine and eating every day until all of a sudden he just died. I know how everybody feels about damsels here, but it really confuses me how this could have happened so quickly. He was really small (one of the smallest in the tank) but he had a couple of friends he'd hang out with. None of the other fish in the tank are having any trouble.
I don't think I'm adding any new fish to the tank until I get more live rock. There's clearly a lack of hiding places that aren't taken already and I don't want to chance getting another cardinal until he at least has a place to hide during the day. It's just tough to find them around here so I don't know when I'll get another opportunity :-(
