When goldfish die in your aquarium they do indeed float to the top of the water. Do goldfish float to the top right away? No. You’ll usually find a goldfish that has died lying at the bottom of your fish tank. If you leave goldfish that died in your fish tank for a long period of time they will float to the top due to the body decomposing producing gas internally.
Whenever you notice a dead goldfish in your aquarium remove them right away. If you don’t this can cause poor water quality and your other goldfish could get sick with fish diseases and parasites. Remove any dead goldfish in your aquarium right away to keep your fish tank healthy and disease free.
****If you ever find any dead goldfish in your aquarium investigate and find out why they died. These are your warning signs that something is wrong. If you don’t react and have other goldfish in your tank they could be in danger of dying. Test your water quality in your aquarium right away to prevent any other deaths from occurring. One dead goldfish could mean more. ****
