I recently bought 16 cardinals from petsmart. They looked pretty healthy and had survived in their tank for a week or two.
I brought them home to my 54 gallon and things initially looked good; i.e., by their schooling and swimming in the open they seemed to have acclimated. (On previous occasions poorly acclimated cards seemed to find a corner and hide on me.) Five days later 13 are dead and one more appears marked for death. The precursor to dying seems to be a disappearing caudal fin.
My tank recently cycled and has 0 ammonia and nitrites. It is heavily planted as well. While petsmart uses harder municipal water, mine is about 5 kh. Like I said, though, they seemed to do great initially.
The question is, then, should I go to liveaquaria for cardinals and expect better luck or would there be trouble within my tank? BTW, ottos and corys from petsmart are doing great and I know ottos can be pretty sensitive.
Thanks for your advice.
