Cory with maybe fungus?

Sorry the pics aren't great but can anyone tell me if it's a fungus? How it happened and how to get rid of it?

Hello nik...

Fish problems are water related. You must keep the tank water pure all the time. The way to do this is to remove and replace at least half the water every week for smaller tanks. Larger tanks over 30 gallons can normally go 2 weeks between large water changes.

Up the water you change and add a healthy herb supplement like minced garlic. My Corys love it and it contains many nutrients and a natural antibiotic.

Sorry I should've included more info. The tank is a 40g tall. It has a penguin 200 hob filter and 2 diy filters that my husband made with my airstones in plastic bottles w/ sponges and bio balls. The pH is 7.5 am, n2, & n3 are all at 0. 30% weekly water changes w/ gravel vac. Tank mates are 4 sterbai Corrie's, 5 blk skirt tetras, 2 serpae tetras, 1 Columbian tetra & 2 electric blue rams. The Cory in the pic is the only one showing symptoms and hes acting normal, just has this light brown fuzzy looking stuff on him :-\ Could it be because we made my airstones into fliters and now there's less movement at the bottom? That's the only change we've made recently and its been about a week but I didn't notice the fungus looking stuff till today.

Is it a cycled tank? I always find N3 at 0 odd. Is that from a liquid test or strips? If ammonia is 0 than filters ok but possible the change triggered an infection. Have you checked ammonia?

I honestly can't tell from the photos but more water changes never hurt. IMO I would assume fungus and start treating for that with meds. If no improvement within 3 to 5 days, switch to meds for bacterial infection (likely gram negative).

Try googling " brown fungus on FW fish" and see if you can find something that matches. Those pics are pretty blurry.

Looks similar to this but not as advanced and brown instead of white. I did a water change and added pimafix last night. I have both liquid and strip tests but I generally only use the liquid because the strips don't test for ammonia. I got the tank second hand back in February and it was filthy so I cleaned everything, gravel, filter, etc. Huge rookie mistake, I know. Its been up and running since February and I test the water twice a week just before a water change and the day after. I've never gotten any readings above 0. So no I don't believe the tank is cycled and the fish are pretty much swimming in treated (prime) tap water. Not sure how to fix that, just give it more time? Cut back on water changes? I've stopped changing the filter pad and just swish it in the dirty water bucket.

So I was browsing the forums and it seems I've been testing wrong. So I tested all my tanks and this is what I got... In order of appearance - 10g 20g 40g 40g the 3rd one w/ the higher n3 is where the Cory is. So I guess all my tanks are cycled and probably have been for some time. I'm just surprised I never saw any ammonia.

Yeah, I searched Google and found that pic of a koi that has what looks similar to my cory cat.

Ime pimafix is not suitable for advanced cases. Try it but if not working I'd shift to a stronger med.

Does it come and go - were you thinking fish pox (even though more in cold water fish for that)?
