Anything dead in a tank will go rotten and poison the water. This could kill all the occupants of the tank. It MUST be removed immediately.
Don't even think about it. They hate each other and will attack and kill the other one. Only do it if you have a divider.
well not exactly if you want to kill your other fish then........sure! why not? if love your fish, why kill it?
Fertilizer rnoff can kill fish by darkenning the water and not allowing sunlight to come through. If sunllight can not come through, SAV's(Submerged Aquatic Vegitation) dies. Most fish eat SAV"s. If the primary source of fish food is dead, the fish die too.
because when we fish it can kill other fish
yes betta fish have to live alone or one will kill the other.
One is caused by humans, the other is not.
they dont eat other fish they just attack them to kill
Yes, Betta Fish are extremely aggressive and they will most likely kill your other fish.
i think
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.
Fighting fish are territorial and can be very aggressive, they will kill other fish if you put them in the same tank.
They can. Any animal can carry bacteria, and infect other animals with it.
