Feeding recently dead fish to other fish

  • We are currently upgrading MFK. thanks! -neo
would you feed a cotton wool fungus covered fish to another?

i def. would not lol... u could prob freeze it first and then feed...as this is a common practice of disease prevention/transfer when feeding wild caught fish to aquarium fish... but if u can clearly see ick/fungus id steer clear.
 
Personally I would not feed a dead fish from one of my tanks to another fish. The risk far out weighs the the reward so why bother.

If one of my fish got killed by another fish and I've seen it and I couldn't stop it in time. Yes I'll feed it to my other fish. If it died and I don't know what happened, no it'll go right in the garbage.
 
Bad idea. If you know the cause of death, that's one thing. But a mysteriously dead fish could be a time bomb, you definitely don't want to feed that off.

It also depends heavily upon the immune system of the predatory animal. If it's a wild caught fish, and it's eaten live food its whole life, it's more likely to be able to fend off pathogens that it'd pick up from scavenging a dead fish. But if it's a captive bred pellet feeder, it's more susceptible to parasites and pathogens because its immune system is not as strong.

However, there are still some diseases that could possibly be transferred. It's your choice, given that information... but it's not a good idea.

That being said, when I have an invert that dies, I always feed it off. My pike cichlid got my last crayfish after it passed on, and my blue tongue skink has eaten a crayfish and a few breeder hissing cockroaches. Most (not all) diseases that may kill an invertebrate are unlikely to be able to attack a vertebrate, due to their biological differences.
 
Were we just lucky or is he right?
Hello; Luck. It is one of those things that works well right up to the time it does not.
How the fish died would be a major factor
Hello; Disease and internal parasites being the likely big risk.

Hello; Those things said I have had fish die and go unnoticed for a time. The snails and other fish often found to have eaten on the corpse. The risk of a disease spreading in the same tank by such feeding probably not increased over the the fact the other fish are already in the same water.

Putting a dead fish into a different tank seems to be a way to spread problems.

We each get to run our tanks any way we wish (so far). Good luck and keep us posted if things go bad.
 
If the cause of death is unknown, it's not worth the risk. If the cause of death is physical trauma, go right ahead.
 
Totally agree that plopping a dead fish from one tank, to another tank offers more risk than reward. So many factors could have lead to the death of the fish. Was it a parasite? Was it due to the effects of long term poor water parameters?

Fish that scavenge in nature is different than scavenging off a captive kept fish.
 
I recently did this! one of my fish (fry) probably an 1" died from aggression in the tank. He was getting picked on then later saw he was barely moving and then took him out and he died in his own tank. I just fed him to another fish. I know for a fact he died from trauma and not a disease. Very common when your growing out fish to have casualties.
 
I used to have a really good pic that i liked to show of a pretty big internal parasite that took up most of a tetra's body inside...

Anyway, my point here, like some have pointed out is if a fish died of unknown causes (possibly internal parasites for example), then you could be asking for a whole load of trouble if that spreads and you have to deal with internal parasites...
 
Any fish coming from an aquarium/aquaculture setting would have a increased chance of parasites unless treated...I would stay away
