How do fish decompose?
The fish fills his bladder by ingesting dissolved oxygen (DO). After the fish dies there is no more DO being ingested and the air in the bladder starts to dissipate, causing the fish to sink to the bottom. After a few days, the internal organs of the dead fish decompose and a gas is formed.
What happens to a fish body when it dies?
Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
How long does a fish take to decompose?
For the whole dead body to be gone maybe 7 to 10 days. alot will depend on how long your tank has been established. If over 6 months you should not get an ammonia spike from that size of fish.
How is decomposition of fish identified?
Decomposition in fish, such as tuna and mahi-mahi, is detected by organoleptic evaluation. It is also indicated by elevated histamine levels in the muscle tissue. Histamine forms postmortem by bacterial action on the amino acid, L-histidine.

How long does it take for a human body to decompose?
Normally, substantial decomposition mostly occurs in the course of two weeks, and the body’s soft tissues start disintegrating even with preservation. If the body does not get enough protection from the elements, it can even skeletonize in a space of a year.
How long does it take for a dead body to float?
In waters like the Arabian Sea (tropical waters), the story is different. Even a heavy weighted body floats to the surface after 3 or 4 days, and it is exposed to the sea birds and buffets from the sea waves. Scavenging and putrefaction creatures dismember the corpse in one or two weeks, and this eventually sinks the bones.
