Methods for the Disposal of a Dead Fish

The worst part of having a pet is its shorter lifespan and the cute little companion parts with us after a few years of happiness. It is applicable for our aquatic buddies too.

Many aquarists seem confused about the right way of disposal after grieving for their pet fish. Along with the care guide of the aquarium fish, you need to know the correct way of their disposal, too, so that the environment does not get harmed.

Respectful Disposal

Aquarists consider their pet fish as their family members, and they want to dispose of its remains most respectfully.

At present, there are multiple ways of disposal of a dead fish, like flushing it down the toilet or throwing it in the trash or keeping it at an open place so that animals can eat it. However, these are not the preferred ways for the aquarists. Flushing is considered illegal in some places too.

Most of the aquarists take the dead fish to the doctors for advice regarding the place of cremation or burial. Alternatively, some aquarists often choose to bury the fish in their own house. The way of disposal depends on the mentality of aquarists. Some prefer economical ways, and some others prefer respectful disposal.

Burying is considered the most respectful way of saying goodbye to your aquatic pet. If it is your preferred method too, but you are confused about how to conduct this, you can follow these steps:

Observe and Remove the Fish

You are previously observing in case the fish was suffering from any disease. Else, you need to observe to confirm its death as some fish may act. Once confirmed, immediately remove the fish to protect others in the tank. It will be better if you can remove the whole fish with a single attempt as sometimes, shortly after death, the fins split. You will need to remove the parts from water too.

Preserve the Fish

Keep the fish in a paper bag to get some time to arrange disposal. You can preserve the dead fish by placing the paper bag in the freezer to protect the body from rotting. It will allow you some time to identify where (in your own home or pet cemetery) you can bury your pet.

Prepare Burial

At present several environment-friendly caskets are available which come in different sizes and offer a seed to plant in memory of your loving fish. You will get these at the stores and online.

Grave of the fish can be 10-20” deep to prevent street animals from digging the soil and eating the dead fish.

If these caskets are not available, you can bury the fish in a Ziploc bag. However, these bags take much time to decompose, so you can bury the fish right after taking it out from the freezer. You can plant a seed as well.

Some aquarists prefer to build a special monument with a special message written on it. But it is optional.

Taste Water and Make Necessary Changes for Other Fish

Maybe the fish died because of some mismatches in aquarium water. So a water test and making some changes can save the lives of others. You can change the water, filter clean, or gravel vacuum to remove toxins of the dead fish right then. Alternatively, you can apply probiotic bacteria supplement too for the healthy upbringing of other fish.  

It may sound sad, but if the dead fish was shoaling one and the tank mates were of similar ages, and if the cause of death is its age, some others may die soon. It’s your responsibility to dispose of them in the right way.
