well this sucks...I seafood cycled my 90g.
Amm. and Nitrites read 0
Nitrates read 15-20(possible problem?)
after a 30-35% PWC
I added 40-50 lbs of LR
a little over a week ago and it appears pretty much cured. An emerald crab has been cruising the tank and appears fine.
I added a clown fish 2 days ago and seemed ok until this AM when he started swimming circles, head toward the bottom of the tank, appears to maybe be gasping, but I guess he kind of always looked like that; dies with in a couple hours w/ some purplish shading across the body.
I also noticed this AM he seemed to be producing a long trail of excrement.
My initial concerns were the flake food I gave him. It was the same stuff I use for freshwater fish...some tropical blend.
Secondly, my skimmer seems to be sending hundreds of really small bubbles around the tank.
Any of this point to a possible cause?
I bought the fish at a large pet store chain (I know, I know) but I almost exclusively worked w/ someone there who actually steered me away from buying a couple times until the tank was ready.
