Hello- I'm hoping your knowledgeable staff might be able to answer a question for us, please. My daughter has a goldfish that she has had for 3.5 years (won at a county fair). These last few months or so he's (she?) had a bubble growth growing on the top of his head. This last week we noticed parts of it are starting to turn black. Can you tell us what this is, by chance, and if there is anything we can do for it? We were thinking a tumor of some sort maybe? :( I've attached some photos I
Hi and thanks for your request and pictures. This tumor like lesion could be due to a lymphocystis. This is a virus (herpes), mostly seen in goldfish, which can cause these type of cauliflowers mass-like lesions. Of course to be confirmed, this should be sampled and or removed completely. Unfortunately these masses can grow much bigger that the one showed in the pics and can become infected. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!
