No, sometimes they float on their side. But some whales have "negative bouyancy" which takes them to the bottom when they can no longer swim.
When they float to the surface it means they are starting to go rotten and fill up with bacteria. I guess the fish has been dead for some time.
Sometimes they do. The decomposition process may sometimes produce gasses which become trapped in the body/flesh/frame of the fish and cause it to float.
Not neccessarily.
Hundreds is typical although some will die young.
The life cycle of a betta Fish goes like this: *They hatch *They live *They die
Yes
Betta fish get in fights with fish with colorful fins and bodies. If your betta gets in a fight while your away,the weaker fish may die. But if you see your betta fight with another fish you should try to split the two fish apart [or all the fish that are fighting].
it will be sick but if it continues then your betta will die.
Bettas can die at any time.
I think so
no, one of the fish will get attacked and die
Betta dish actually don't sleep, or they'd die.
Betta are airbreathers. So long as the ammonia and nitrates are okay, you don't need filters on a Betta tank.
I've had two guppy fish die and they have both sank
Because, if they are in a small cage the Betta will stop growing. But, the organs will keep growing and the fish will die a long and painful death.
