If it seems that the fish is attempting to swim upwards your fish has a swim bladder problem. Your fish will die from this eventually. Pet stores may well attempt to sell you something to fix this. IMO you would be wasting your money. I would destroy/euthanase the fish.
yes, crabs can swim left, right, upwards and downwards
You probably scared it
Angelfish swim primarily by using their pectoral fins, which they flap in a rhythmic motion to propel themselves through the water. Their streamlined bodies allow for smooth movement, while their dorsal and anal fins help with stabilization and steering. By adjusting the angle and speed of their fin movements, angelfish can navigate effectively in their aquatic environment. This combination of fin movement and body flexibility enables them to swim gracefully and efficiently.
no some swim upwards however they cant swim backwards but.. they do like to try. Whales have huge dongs.
No, the density is too low to provide the upwards force needed.
To get to the other side! Where did you get the back and forth kind? Mine only swim to and fro. In semi-seriousness, angelfish in their natural habitat have freedom of movement and exercise that. In an aquarium, back and forth is the only way to go. If you will allow a moment of anthropomorphism, they're probably looking for the way out.
with there mouth open
because its probably sick and need to see a vet... if this continues notify your vetit probably has some kind of diseaseMost likely a swim bladder disease
no. EDIT: Incorrect. Fishyfisher82 has a two year old veil angelfish in a 36gal tank (and all the size that implies) with a trio of glass cats who have been coexisting for well over a year. So long as the fish can swim quickly and are not too tiny, and you only have ONE angelfish, you're fine. Angelfish will most likely eat guppies, though.
The penguins swim fast with their beaks pointing foreward for hours.
For the most part you are looking at mid level for an aquarium. However they do go everywhere. My personal stocks I have seen tend to go more upper level than lower when not in the middle.
When you swim, water enters your body through your mouth and nose as you breathe and move through the water.
