Nano fish that swims in open, top half of tank?

[lastlight]

in my tiny as heck tank? lots!

As for the royal gramma...I bought one from Golds when I got the blenny. he ate so well for a week and i just up and found him dead one morning.

I actually DO have a second one in the tank right now. From same batch as the first but months later. so was at golds for months. Looked fine and boom after I added him he looked terrible hours later. He's hiding in the rocks and I have yet to see him swim. He looks to be doing better than day one when the current was somewhat carrying him.

All my other fish are doing rad. baffles me.

I'm ready to go back to an orchid dottyback if this guy doesn't make it. beginner fish...not sure wth is up with these things in my tank.
