Swim Bladder Disorder: How to Tell if Your Floating Pet Fish is Dead

stop-your-pet-fish-may-not-be-dead

Have you ever found your pet goldfish floating listlessly at the top of the tank on its side? Most people who make this discovery assume that little goldie has passed on to the other side and immediately scoop him or her from the tank and toss them in the toilet for a traditional goldfish funeral. Unfortunately, in many cases the fish isn't actually dead, but rather suffering from a problem with their swim bladder due to over feeding.

There are plenty of warnings about over feeding fish, but many people are unaware of just how easy it is to over feed. The danger of over feeding is that it can lead to constipation, which can in turn lead to problems with the fish's swim bladder.

The swim bladder is an organ that is flexible and filled with gas. Fish use this organ to maintain their buoyancy in the water. The gas expands in lighter pressures, helping the fish to rise, and is compressed when the fish dives, which helps it descend into deeper waters. Problems with the swim bladder can lead to the fish floating on the surface, sitting at the bottom of the tank, or even standing on its head at the bottom of the tank.

Remedies:

If you find your fish floating on its side, not feeding it for three or four days can often solve the problem as the fish's body recovers from the gorging and rights itself again.

Feeding small deshelled peas can help alleviate constipation, which in turn will help the fish's swimbladder to work effectively once more.

Prevention:

The problem may also have been caused by the fish swallowing air, so pre-soak the fish food in future to avoid this problem.

Feeding a fresh diet as opposed to fish flakes or pellets might be beneficial. Bloodworms, brine shrimp, and even small amounts of vegetables can help your fish be more healthy.

The most important thing you can to to prevent these problems is to regularly test your water, and ensure good water quality.

You should also change your water frequently (the 50% per week rule holds here), and ensure that you do not stir around in the gravel when you change the water. Doing so can unleash nasties into the water that otherwise would stay trapped in the gravel.

Never use water straight out of the tap. Instead use a water conditioner and test the water for the correct pH before adding it to your fish tank.

This has been a basic article aimed at the beginner fish keeper. I know I wish I had known this when I was keeping fish as a child, as I am sure I killed at least one fish unnecessarily who may have simply had a swim bladder disorder.

Animals exhibiting signs and symptoms of distress should be seen by a veterinarian immediately.

Liam Swift on May 13, 2020:

I have checked all of my water and everything is clear, however 3 of my fish have already died and one is lying lifeless. I don't think it was all because of a bladder problem and I don't know what to do

Bryson Gooden on February 28, 2020:

I have 3 guppys and i think i flushed one of my fish that was still alive..... i woke up and he was inside the filter intake but didnt look hurt and i think he got hurt then got sucked in and i put him back and he just floated there on his side so he might have still been alive

My fish was fine yesterday, eating and swimming around. (He looked a little tired last night but I don’t know) but I woke up this morning and now he is on his side on the bottom of the tank, I have many other fishes however he is the only affected.

Anna Shannon on April 11, 2019:

Thank you so much for this. i have got some baby fish in my pond and was so upset to see they were lying on their side. I want to do my best for them.

My fish was fine yesterday, eating and swimming around. (He looked a little tired last night but I don’t know) but I woke up this morning and now he is on his side on the bottom of the tank, he is an only fish. Also, this morning I came into my room and my cat was on the desk so maybe she scared him.

I don’t think he is breathing but I can’t be sure. If he is stressed I’m afraid that if I try to wake him up or move him it will cause him to become even more stressed and die ( if he hasn’t already). I need help.

Paytc on May 05, 2018:

My goldfish is going upside down, laying on the rocks for 2 days and she is not dead yet because she is still swimming a little bit but he is going to the top and bottom of the tank// switching about every 3 minutes, and laying there. Is there anything I can do? At all? Do you happen to have any idea what the problem may be?

Dat goldfish lover on December 07, 2017:

Susan on October 26, 2017:

Kelsey ---- on December 23, 2016:

Hm... My poor Undyne is still having a problem. Is there anything else I can try?

superfreak on July 26, 2011:

BUT WHAT IF NOT FEEDING DOESN'T WORK AND HE ACTUALLY IS DEAD :(

Yes, pet stores and private people selling fish should really supply this basic informtion, and it is incredibly basic.

Rebecca Mikulin from Sheridan, Wyoming on January 31, 2008:

Great "basics" article! It's sad how many goldfish are inadvertently abused due to misunderstandings about their space requirements, feeding, and common ailments. I also feed mine spirulina flakes regularly to help prevent SBD, not as easy to obtain as the peas but if you run into a fish that won't eat something so different than what the pet store gave it it's worth a try :D

Hope Alexander (author) on January 30, 2008:

As a child I didn't know either, which seems very silly, as this is a very common affliction amongst goldfish and other commonly kept pet fish. It seems very remiss of pet shops to sell fish without this sort of vital information. There are probably thousands, if not millions of fish killed every year needlessly because the owners had never heard of this problem.

Stephanie Marshall from Bend, Oregon on January 30, 2008:

Ah ha..... I see now. Thanks. I never knew.

Just Toyia from Tennessee on January 30, 2008:

I had a fish with this problem and nothing helped her except temporarily, but she lived for 2 years -I wrote about it here a few weeks ago-
