SICK CORY??

[flames9]

10 gallon tank, all water levels are good. had 1 Cory, 2 otto's and 5 guppies. Bought another cory yesterday. Woke up this mornign and it was dead!! so back to 1 cory. NOW this 1 cory is swimming slowly and very lathargic and seems to be red by its mouth. A few weeks back, I thought it was going to bite the dust, because for a few days it barely moved,but then seemed fine, until now!! Any ideas?? Thanks

First thing to be done is to test your water for ammonia, nitrite and nitrate, as it will help very much in diagnosing the problem.

I will also move this over to the Unhealthy forum.

when you bought the cory, did any other cories in the tank look sick?
