My goldfish's mouth looks red & possibly cut
« on: May 05, 2010, 12:35:30 AM »

Hi there -- I've had my goldfish (Tiny) for apprx. 10-11 years now. He's never had any problems before. In the past 2-3 days, he doesn't seem to be eating & he goes into these 'fits' where he frantically swims around crashing into everything. I'm not sure if he has hurt his mouth in doing this or if something else is wrong. All around his mouth is red and his top 'lip' looks cut. Also, his mouth seems to be open wider then usual & he doesn't seem to close it at all. He's just not acting right. These 'fits' are rough/loud enough that it wakes me at night. 

There haven't been any changes to his tank or feeding habits. Everything is status quo.
Has anyone had a fish do this? Is there anything I can do for him? I feel bad for the poor guy.  Sad

Check the water for pH, ammonia, and nitrite levels ASAP or the fish could die.  An extremely low pH level or high pH level can cause the fish to dart around .  Very low pH level will kill off the nitrifying bacteria, causing spikes in nitrite and finally ammonia, both of which can be lethal to goldfish and cause the symptoms you are describing.  If the pH is extremely low, bring it up slowly or you will cause the fish to go into pH shock. If the ammonia and nitrite levels are high , perform partial water changes to bring them down immediately.  If the water parameters are just way off, you may have to move the fish to temporary container with new water matched to the same pH as the existing tank to prevent further damages to the fish from the toxins and then slowly adjust the pH back to normal.

I suspect poor tank maintenance as the root cause .If the fish manages to survive you will have to check to see if you are properly cleaning the tank and doing partial  water changes on a regular basis.

Hi Mary,

I would check all water parameters first like Bohrah already mentioned. And act accordingly. Towards this
you also can treat with natural medicine like Melafix and Pimafix according to the instructions on the bottle.

The other thing is and it is a sad thing to think about it; Tiny already had a very long life.
But as the average life CAN be 16 years, let us hope it is only a not to serious health issue  Cry

He's bumping into things? He's either not comfortable with the water parameters, or he might be bothered by some kind of parasites. It's quite likely to be parasites if his mouth has been hurt so bad from flashing (The rubbing on/bumping into things behavior is called like this) it might develop into mouth rot which it might already have done if you say that his upper lip is getting "cut", since mouth rot causes the lips to come off of the face of the fish if it's not treated in time.

So I think it'd be best if you would first of all test the water and treat against parasites if there's nothing wrong with the water parameters.

I think you should check to see if you fish has a piece of gravel or something stuck way back in his "throat".
This is where the food goes to be ground up by the goldfish's teeth.  Take him out of the water and look with a flashlight/pen light.  Hold your fish in a wet cloth or wet net.  If you see something then take your fish's head just behind the gills and gently squeeze.  It should come out.  Getting gravel stuck is a common occurance.  I would then add aquarium salt, 1 Tbs per 5 gallons of water or 1 tsp per gallon and Melafix according to directions to help him heal.  If he doesn't have anything stuck and just cut himself then the salt and Melafix will help him heal quite quickly.  Good luck!  Smiley
