Hi all. Hope someone had help me with this one. My goldfish has developed a bump. I noticed it a month ago and started a course of Melafix by API as directed by the label. It responded well and faded away. Today it has flared up again but is more reddish around the edges/grey in the middle. Any idea what it is and best course of treatment?
Lovely fish. Reminds me of my own (RIP/SIP). Water quality is the key, so, if you're not doing so already, keep water consistently at 0/0/20 for ammonia/nitrite/nitrates respectively (or nitrates no more than 20 above tap water levels), even if this means larger and/or more frequent water changes throughout the week (rather than simply a weekly water change). Another option possibly worth trying might be eSHa 2000. I'm never keen on medicating unless the fish is showing other symptoms such as loss of appetite and less inquisitive behaviour than usual but, in this case, it *might* nip the problem in the bud and also prevent it evolving into something worse. I had an x-ray tetra who developed a problem of what was more an ulcer/inward-facing mark that waxed and waned and became very deep at times - it was a case of "managing" it with Melafix when it was present/re-appeared or eSHa 2000 if it became really severe.
Hi. Yes, she's a lovely fish. She had a poor start in life where she won at a fairground. Not a practice I agree with. Had her for three years' Thanks for the advice, I'll do a water change ever two/three days. Not sure if it's good or bad but the grey bit got bigger over the last two days but fell off when she swam up for her feed this evening. Pinkish/reddish underneath but no noticable hole.
Hi all, Quick update. I think that the issue is dropsy. Lump has appeared now on other side with some slightly raised gills. Water change has been done yesterday, aquarium salt added and started treatment with eSHa2000 as directed. Luckily she is can only fish Fingers crossed.
I'm not sure this is necessarily dropsy. However, something is clearly not right, what with the swelling (which in turn has caused distended scales over the lump) and one side of the body generally swollen.
Whatever it is, eSHa 2000 sounds wise.
I would omit the salt at this stage, though. Aquarium salt = sodium chloride = mild antiseptic (and thus fine for the original lump/spot). Epsom salts = magnesium sulphate = draws fluid out from the body.
If the eSHa 2000 doesn't work, even after an extended treatment dose (5 days rather than 3 days), then Epsom salt dips/baths may be worth a go to try to reduce any outstanding swelling.
