If your tank has become contaminated by toxins or your pets are infected with a disease you may find a few dead animals in the tank. If you do, you will need to take control of the situation before it causes a big problem for the rest of your pets.
You need to be observing your tank on a daily basis. Keep track of the precise number you have of each species. That way if one goes missing you will be able to notice immediately. In the case that you are unable to spot one of your fish, you need to go into the tank and search for the deceased member of your shoal.
Due to the fact that your tank is filled with warm water that is rich in bacteria the body will begin to rot quickly. The decomposing body will cause contaminants to enter the water and puts the rest of your pets in jeopardy. Therefore, you will need to remove the corpse from the tank as soon as possible.
Once you have removed the unfortunate pet it is important that you examine its body. When you see things like ragged fins, a bloated abdomen, or diseased scales it is an indication that there is an issue in your tank that is causing disease or stress. However, if you are not able to remove the corpse from the tank in time it will not be possible to look at the remains. In that case, you need to make a careful observation of your remaining pets.
It is crucial that you take all of the contaminated material out of the water. After you have removed as much of this as possible you need to test the quality of the water. The results may indicate that everything is fine. Or it might show that there are serious problems with their environment. If you find an issue with the water quality you will need to do an emergency water change. However, in some cases, this may not be enough to resolve the damage. If you are at all unsure it is always a good idea to consult an expert who will be able to give you advice.
Finding a dead pet in your tank can have a serious effect on all of the occupants. Make sure that you remove all of the contaminated material and check your water quality to give the rest of your pets a chance to recover.
