I've been meaning to get an account on here but haven't really had a reason to until now.
One of my corydoras is sick, with a small patch of white fuzz on his left side, labored breathing, and clamped fins. He's been breathing at the top more than normal, and sitting more than normal.
My water levels are:
Water temp: 77°F.
I do 25-30% water changes weekly, sometimes more often.
This tank has been set up for about a year, but I moved home from college about 2 1/2 months ago. So I put half the water in hallon jugs and brought it home, and used new water for the rest. Also new substrate, but same filter media.
I also added 4 corydoras within a month of moving back.
I have a 10 gal, with one betta
and 4 corys.
I'm overstocked, and currently doing a fishless cycle on another 10g. I was trying for a 20g but found this one cheap at a yard sale.
My tank had half a dozen moss balls, a small amazon sword, four shoots of jungle val, and some java ferns.
But when I started cycling the other 10g a week and a half ago, i put half the plants in there.
Another note- a couple weeks ago after getting some new plants, i noticed some small white worms in my tank. I did some research and saw that it isn't totally uncommon, and some of the most common ones aren't harmful to fish. There's been a lot more recently, but they stay in the substrate. I've been trying to vaccuum them up, but am not sure what to do except to totally change the substrate and everything. Which I'm going to do a month from now when I move back to school.
I have dosed API Stress Zyme and API Stress Coat into the tank.
I also put 1/2 tsp of aquarium salt
into a 1/2g holding tank, and put the sick cory in it for 10 minutes. He acted normal, and did fine.
So my questions are..
How should I go about treating the cory, and what should I do about the worms?
My new 10g should be ready within a week or so. Fingers crossed.
