I have an established 1800 gallon pond with waterfall, water lilies, and filtration. Bullfrog recently appeared. One the big fish had a small bump on its side. Almost overnight several fish have a bump or two like a small pea. No open lesions. Just noticed a couple now appear to have swollen bodies becasue their heads look small. Normal activity. Treating with AquaFix. These are big beautiful fancy goldfish. Really big really fancy. What to do?

I would google koi pox in goldfish. I wonder if that could be it? I know nothing about it but have heard that it is common and pretty harmless. I hope they come through this mystery sickness just fine!

A few of my goldfish have some bumps also and they just live w/them.

I haven't seen a picture but could be koi pox. What climate zone are you in? Coming out of the cold water, going into the spring and wamer season, these can clear on their own. Koi pox won't kill your Koi, just the aesthetics are annoying. If meds are even needed, formalin & malachite green ( ProForm C ) is quite benign yet affective. Any pics of the bump?

Some bumps are contained within the body and scales. One looks like raw flesh. Bullfrog joined us a few weeks ago and having trouble dispensing him. Native yellow legged frogs occasionally come in from the river. I live in Oregon along the North Umpqua River. Recent;y did a half water change (well water) and added 1.5 cups salt. See pics Fish almost impossible to catch.

I suspect parasites causing the fish bumps from the photo. I don't think the frogs present a problem though they might be harmed by the salt. I like amphibians in my pond (mainly newts but an occasional frog).
