ong jon asked in PetsFish · 8 years ago

at least one of my pond goldfish is losing scales may be do to cat attack may be fungus will uv filter help?

it appears other fish MAY BE LOOSING SCALES ...more than 1/2 the 2000al has been changed last week... 1 fish loosing scales and "skin" appears red/raw has been put in separate tank..

will uv "filter" cleaser help clean pond?

Update:

even as the pond has no filter and i never have put any chemicals in it [ once about 3 yrs ago i used an alge killer] the ph is perfect..ironic because i can never control the ph in my 30 gal indoor tank which i use to grow tini fish to 1"-2" before putting them in the pond

    I would try using a uv filter

    UV only kills what passes through the sterilizer, so it will be ineffective against a fungus infection attached to the fish. In ponds its biggest benefit is controlling green water algae blooms.

    Your problem does not sound like a fungus infection. When was the last time you tested the water? Maybe poor water quality?
