The most humane way to kill a fish is with carbonated water. The carbonation in the water renders the fish sleepy before the lack of oxygen molecules destroy the fish. I read that in a book years ago when I kept an aquarium.. so all you fisherman out there bring a bottle of pop on your next boating trip. No need to make your dinner suffer.
who on this earth would humanly kill a goldfish or any animal
Beta fish do NOT like other fish, they may try to kill the other fish or get seriously injured by the other fish.So probably not.
If your betta is ill and you have not been able to treat it, the most humane method is using clove oil. You may be able to get clove oil at a local store.
It is possible that the other fish injured the subject fish, BUT IT IS ALSO POSSIBLE that the fish with the "hole" had a skin infection which killed the tissue, and as the dead [necrotic] tissue decomposed it "washed away," leaving the hole.
No, they are both aggressive/semi-aggressive fish so if they were in the same tank there is a high possibility one would get injured or die
its obviously fish kill means dead fish ..
After a certain number of days or if it is to aggressive to get adopted they will humanly be put asleep.
Fish kill means fish creek simply means die-off of the fish
no a water pump can not kill a fish
well not exactly if you want to kill your other fish then........sure! why not? if love your fish, why kill it?
If the jar has water in it with the fish, you will kill them.
Plastic decorations can kill fish if they are dumped in to the ocean. (the decorations not the fish)
