Question goldfish with large red spot on head

anybody know what might be causing this i have a small plain common goldfish and recently i noticed two flecks of red under the scales on his head almost like he was bleeding under his scales i checked it again the next day and thought it was gone however i checked again today and to my surprise the red flecks have developed into a large red almost blister looking thing that takes up most of the top of his head i have looked up ulcers on the internet and it dosent look anything like them his tank has been neglected a little lately (i have had a lot of school deadlines coming to a close all at the same time lately) its probably worth mentioning that in the same tank i recently had a 1 yr old ryukin in perfect health just drop dead for no apparent reason i have been doing weekly water changes and it was the day before a chang i noticed the dead fish followed by this problem anyone got any ideas what this might be or better yet how to kill it?

Is a picture possible? How big is your tank? What are your water parameters?

Ummm no wonder. A gold fish in a 12 liter (I don't know how many gallons that is but I know its ridiculously small) WITHOUT A FILTER????

Water parameters doesn't mean temperature, it means ammonia, nitrites, nitrates, and pH.

Your goldfish needs like a 30 gallon tank minimum. And thats just for one goldfish, he is probably living in the worst water quality ever and that would explain the sore. You need to do water changes and get him a new home.

I couldn't tell you what his chances are because I don't know the extent of his injury. How big is the fish now? It sounds like hes grown quite a bit since you got him? I recommend getting a new tank ASAP... Like seriously as soon as possible. Until you can upgrade you should be doing daily 20% water changes. Its pretty much his only chance.... You can add meds such as stress coat or melafix to help the wound heal, the only problem is I would need to see it... If theres a sore and nothing he could have injured himself on then he could have a bacterial infection by this point, or the sore could develop fungus. If you can borrow someones camera and get a picture then do so. It's hard to give a diagnoses with the only description being a sore.

I agree - it's impossible to make a diagnosis without a very good description of the sore or better yet, a picture. Improving the water quality would be absolutely beneficial though. I recommend doing a 50% water change as soon as possible, with the 20% daily changes Little-Fizz recommended after that. Goldfish produce a lot of waste and grow very large so getting him a larger tank as soon as possible is quite important. I recommend reading up on the aquarium cycle and purchasing the biggest tank you can afford or have room for. Common goldfish grow to over a foot in length and produce a lot of waste, so something like a 90 gallon tank would really be best for long-term care.

These guys are right. I kept having a similar problem with my bubbleeye goldfish. One of his bubbles kept turning red like it was bleeding or something. I had him in a 10 gal tank with a filter and did weekly water changes. As soon as he would get better, it would come back.

I took some advise and got a 30 gal tank, he is so much happier now. I have not had any outbreaks since he has been in this tank. So, if you put your little guy in a new home he will be happier and he will get better.

With Goldys you HAVE to have a filter. They produce A LOT of waste. It would also be wise to invest in a vacuum, changing the water often is not enough. you have to clean the rocks too.

If you can't afford a new tank, they are expensive, try craigs list or freecycle you can post and maybe someone has one they are not using. Just do something fast! He will be much happier trust me.

His sores are probably just the quality of water and lack of filter and lack of happiness. Use stress coat, give him a dose and a half at a time, it won't hurt him to use more than the suggested dose.

goldfish with large red spot on head

I read several posts on this "red bump on head" that were several years old.

I have had a regular goldfish for about 3 years. He looked lonely, so I went to WalMart and bought an algae eater and another regular goldfish. Two days ago, overnight, this red bump appeared on the large regular goldfish.

I admit the tank was dirty, about a week. I don't have filters or pumps hooked up, I just change the water in the 5 galllon tank once a week. Never had a problem before.

I first suspected and injury, since nothing else had changed. Then read several forums about bacteria, wens, dirty water, etc. I had been putting a dime sized tablet of "algae food" everyday for the algae eater....so the water was extra dirty.

I saw a post about a picture and here is mine: goldfish MooPig or




The bump is definitely under the skin right between the eyes. He is very healthy, active and eats a pinch of fish food twice a day. In all respects he is ok, except for this "red bump".

Help ! I don't want to douse the tank with ( light gravel bottom and some glass beads) chemicals unless I have a better idea of what this is. I hope it is just a Wen...

Thanx and MooPig thanx you too.
