Goldfish tumor?This comet developed a tumor on its side over the winter. Any idea what it is? Acting normal and frisky.https://twitter.com/mflinner99/status/877871488954707970 mflinner 2017-06-22T13:11:23+00:00 Share This Story, Choose Your Platform!FacebookTwitterTumblrGoogle+PinterestEmail About the Author: mflinner 4 Comments Venus June 23, 2017 at 9:22 am Log in to ReplyJennifer, Your remedies should arrive today; if not today, for sure tomorrowI sent you the mean green, the garlic, the health tonic and gel food, along with a bottle of Oop Boost. I also included the aloe. This fish is getting the worksI would start with the garlic treatment combined with the health tonic; their a natural together. Use 1/2 ounce of each per 10 gallons of tank water. As long as you’re still having to top off the water, there’s no reason to perform a water change unless nitrates need loweringPerform the treatment daily until you run out of the two remediesWhen you arrive, warm the fish up using the mean green combined with Oop. Use one ounce of each per 10 gallons of tank water.Perform this treatment daily until you run out of the mean greenI might wait to make up the gel food until you’re moved. which by the way, if you need instructions moving the fish, post, and I’ll advise. We want to keep the fish and the pumps coldYou can either combine the aloe with the mean green or do it after; either or Venus June 22, 2017 at 1:08 pm Log in to ReplyIf that whitish coating came off the fish with a touch, it was fungus; bad bugs indeed, but considering the issue with the prefilter, it could have been ammonia poisoning. Friendly bugs that perform the nitrogen cycle live in our pumps and filters, and one goes down or is removed, there could be a spike in the cycle. Most spikes occur after a filter has been cleaned, or the fish are not fed for a few days with no other food source available. Leaving town; if a neighbor of friend was feeding, they may have gotten overzealous, which could cause a spike also.Do you understand the nitrogen cycle, and test frequently for ammonia, nitrites and nitrates? If not, read our 10 Steps found here to learn more https://goldfish-emergency.com/gfe-knowledge-base/goldfish-care/Ammonia burns fish, causing them to turn whitish, but later it turns black as it’s healing, then finally fades away back to the original colorI think you should be able to handle the stocking level. If you see signs of spawning, one fish chasing another, foaming on the surface, withhold food for that day, and they’ll eat the eggs. This is a big problem with ponds. The fish spawn frequently, then more and more fish join the school. lolThere’s a very good chance the tumor is caused from supersaturated gases; not a tumor at all, but a cluster of tiny bubbles under the skin caused by supersaturated gases. These gases are caused by pressure in tap water. Test your freshwater source by filling a clear glass. Let it sit for a few hours. Do you see tiny bubbles accumulating on the glass? If so, this could be an issue, as they typically enter the fish’s body causing a multitude of issues. If you’re using a nozzle on your hose, this could be the causeIf this is the case, the cure is simply to stop adding SSG to water. Run the water on a slow stream; test glass again for bubbles. They’re tiny, so look closely. If you don’t find these bubbles in your water, your fish could have an actual tumor, which isn’t really the biggest deal. Most tumors are noncancerous.If you find you can’t handle the fish (that’s okay) we should take preventative measures for both SSG and cancerous tumors as wellIf you’re able to handle the fish, and the lump is squishy, it’s SSG. If it’s firm, it’s a real tumorLearn more about SSG here https://goldfish-emergency.com/supersaturated-gases/Looks like you have some really good water movement, which helps oxygenate water. Oxygenated water discourages bad bacteria and fungus. Other than the tumor, the fish look great mflinner June 22, 2017 at 10:44 am Log in to ReplyOhhh , never touched the fish before – they’re tough to net. I’ll try. It does look to be under the normal tissue. Noticed it this spring, don’t think it’s changed since then. I did have some water problems this spring, combination of lots of debris in the bottom, and a detached prefilter while I was on vacation for 2 weeks. Some of the fish got a bacterial infection, whiteish coating, and 4 of them died ( out of 20) I treated the pond ( 800 gallons) with melafix , mucked out the pond and they all seem to be doing fine now. I have about 15 comets now, 5-7″ long. That’s not too many is ti? Venus June 22, 2017 at 9:22 am Log in to ReplyHere’s a few questions that will help us determine what it is, or isn’t. Scoop the fish up in a container, and examine the growthWhen you press on it, is it firm or squishy?From the photo, the tumor looks to be under tissue that looks normal; is this right?When did you first notice? and in that time, has it grown?Leave A Comment Cancel replyYou must be logged in to post a comment.
