Big lump goldfish

Big lump goldfish opposite side

Big lump goldfish on the opposite side now and it’s large. Over the last 2 weeks I have done:

Back to back garlic in the tank

Mint in the tank

Baths: 2 weeks ago: garlic and salt (2), mint and h2o2, h2o2 and 1 tsp salt, just h2o2 last night, with massages to the lump.

Lump is soft, but has no head. It’s all under the scales. No sign of pineconing.

Started green garlic juice orally last night and she looked much perkier this a.m. Lump has stopped growing.

    The testers we buy at the pet shops are cheaply made, even the better brands. KH reads 20 to 40 ppm lower than the actual measurement, so I would say your levels were at 140 to 160 ppm. Even though this is considered a little high, it’s not high enough to endanger the fish. KH burns fish, leaving the same white marks that ammonia does

    You may notice the dorsal fin pulled tight to the body

    Just like ammonia, KH burns cause the gills to swell, keeping fish from getting the oxygen they need. The gills typically redden when this happens. As for other symptoms, I don’t know of any

    Fannie has been back in the main tank for maybe 5 days and is doing very well. All symptoms gone for now and tons of energy. It’s good to see. My first Dropsy success. Io is now in the QT tub, really swollen on the left. I’m doing tonics in both tanks. Dandelion currently. And, it’s, antibiotics for Io. Same symptoms Fannie had.

    I’ve been rereading your last post and remembered there were some peas a while back that were kind of slimy when I got them out to feed. I dumped them, but had fed them the day before, so who knows. Now I’m making tiny batches s so they only last three days.

    The only other thing I can think of is that KH was 180 for a couple of days before Fannie started showing symptoms. But I don’t know that that would cause these symptoms.

    It’s possible there’s an issue with the pipes in your home. By the time city water reaches your house, the chloramines added may be too weak to kill off whatever, still, unlikely. Most bad bugs make their presence known by clouding the water, slime on surfaces and so forth; not all however

    I’m not sure how a fish would react to food poisoning; peas or gelatin that stayed int he fridge a little too long. I’ve pushed it in the past, and the fact is, some food comes to us contaminated

    The lucky bamboo could be leaching some unknown substance, causing some internal damage that has caused infection. Some plants are toxic, but I would imagine you checked before adding them to the aquarium?

    You can bet the similar symptoms in the two fish are related. I mean, what are the odds?

    I might be tempted to take a sample of your tap in for testing. We could rule that out anyway
