My Corys Pectorial Fins Are Disappearing!

[bristlenoseitplecoman]

Hey all! Over the last month I have been treating my corys for some mystery disease. only they have it and it has covered the fins under there bellies. I have been treating it with Paraguard which treats fungal, bacterial, viral, and parasitic infections. well I noticed over the last week the fins have been getting shorter. Is there a disease that does this? I know it is not the ich because it is too large. please help.


Tank size: 10 gallons ( planning to upgrade to 40 gallon in the next year)
pH: 6.5
ammonia:0
nitrite:0
nitrate:20-40
kH:80-120
gH:180+ ( I know it is too high)
tank temp:78 degrees F

Fish Symptoms :skittish, a changing color between green and gray, pectorial fins disappearing and covered in white

Volume and Frequency of water changes:30% water changes every 5 days

Chemical Additives or Media in your tankaraguard, stress coat (to heal fins), and carbon media

Tank inhabitants: A Bristlenose pleco (Male), a jumbo neon tetra, and two emerald corys. Don't scold me I didn't know corys needed to school and I had more tetras when I didn't know about cycling and I know I am overstocked. I'm getting the 40 Gallon to get more corys and tetras.

Recent additions to your tank (living or decoration):I recently lost my snail but they had the disease before his death.

Exposure to chemicals: Paraguard and stresscoat

Please reply. any thoughts accepted.

From what I can tell of the active ingredient in this med would not be one I would even consider to cure a lot of what they claim it will.

ParaGuard™ employs a proprietary, synergistic blend of aldehydes, malachite green, and fish protective polymers that effectively and efficiently eradicates many ectoparasites on fish (e.g. ich, etc.) and external fungal/bacterial/viral lesions (e.g., fin rot).

I think you need real antibiotics. SeaChem should be ashamed of itself for hinting it would help with fin rot etc. I use a number of their products- I would not accept a bottle of Paragard as a gift.

i would be using real antibiotics if I knew what the disease was.

I used a mix of melafix and pimafix to treat fin rot and it stopped it after about 8 days. Don't use much though as it is a very strong medication!!
