I went to the LFS, they credited me for the two hatchets after they tested my water and it turned out fine.
I was going to replace them, but they only had one hatchet on-hand so instead I picked up 5 Flame Tetras (sold as Von Rio tetras), instead of the Cardinals. The cardinals they had on-hand had neon tetra disease and I've been wary of the cards anyways, plus the VR Tetras are beautiful. There are a couple varieties, mine is yellow in the front with a diagonal fade to red on the back. I acclimated the VR's and they fed right away, and seemed to enjoy swimming the length of the tank. I'll get 2 more tetras and 3 more hatchets next week.
The last hatchet, which had been bullied non-stop, was dead when I returned from the LFS and it looked beat-up too. I might have to switch out the big mean one.
I'll update w/ pics sometime soon (Monday at the latest).
The LFS had some awesome Cories on hand. Red Laser Cories, but for 12.99 each I think I'll pass. They're really cool, but Cories are the least exciting fish that will be in my tank (IMO - I do think they're cute though!) so no reason to spend $52 on 4 fish.
