If the fish died from a disease, the corpse poses a health risk to the animals that consume it.
Can fish recover from lack of oxygen?
Additionally, a few ice cubes placed in a zip-close bag can be placed in the tank to help drop the water temperature. Be sure not to lower the temperature below the fishes’ normal temperature range.
Do fish get thirsty?
The answer is still no; as they live in water they probably don’t take it in as a conscious response to seek out and drink water. Thirst is usually defined as a need or desire to drink water. It is unlikely that fish are responding to such a driving force.
