Those poor fish. I won't go too far on that because I put fish in to cycle. Now I know better. If you can, take them back to the LFS
and try to get a credit. I fear you will lose them.
I would really ask you to get a good book like The Saltwater Aquarium Handbook or The Complete Marine Aquarium and read.
The tank is just now sarting to cycle and it is going to get much worse. The ammonia is just now showing up and it is going to get higher before it is over. Then you are going to battle nitrites. The salinity is too low for me, I keep mine at 1.024 and the temp at 82 to 84*.
I know others are going to get in on this so I will let them. I am serious about the reading part. Patience is a virtue.
