They tend to be slow and gracefull in their normal state but when being chased or fighting they move and strike very quickly
maybe you can put a non-aggressive fish that if physically provoked by the fighting fish it can defend itself. or fast moving fish like goldfish so it can outrun the fighting fish. when feeding your fishes they usually move quick, putting their mouths above water. however, the betta doesn't. and they can get easily annoyed when other fish bump them. so,I recommend the angelfish.
It may be, but look for other signs. Does it move at all when you move its tank or bowl? Can you see its gills move? Watch it for a whole hour to see if it moves. If not then it may be dead.
Swordfish often fight each other for the right to mate with females or for territory. These fish are very large and very territorial and will often even fight with humans who enter their area.
For the most part they are more active, they move around more, and they build a bubble nest.Also the fighting fish circle around each other and the male will show some of his dance moves off and act cool.Fighting fish will circle around each other and one of them (male) will show off his mating call or dance. As well the female fish will do a famous Chinese fighting fsh ritual dance.*i have seen them do this*
All domestic cats can reach a top running speed of 30mph.
The size, shape, and fins make the fish go fast. Some are build for speed and have special 'fins' on the top.
If they move to fast.
the smaller they are the less resistance to water and the faster they move.
the lawn mower push! repeat this fast on their face.
think its slow...
it means they are having trouble breathing
the thing that makes a sail fish fast is its sail and body shape
