well. the american bison used to be endangered for their furs, but then people started preserving them, and now they are back in the wild.
Because they are so popular for aquariums AF
yes
Nope.avi
silver/bala sharks get on well with most fish and are great in a community tank .
There is no such thing as an "air blubbler" in a shark.
to the size of the tank or bigger AF
They live in around 75-85 degree temperatures
sharks are exotic animals so you cant buy one and keep it as your pet, however you can go to any local petstore and they will usually have bala sharks
Bala sharks grow into large fish. The basic rules are. :- 1 inch of fish needs at least 1 gallon of water (a single Bala shark needs at least 20 gallons. 2 need around 40+gallons). Every tank needs a permanently running cycled filter. Every tank needs to have at least 50% of its water changed every week. Different species of fish need different temperatures (Bala sharks need around 75F) and different pH and specialised foods if required (Bala sharks are omnivorous). If you supply your fish with the above they should survive reasonably well. If you fail to supply what is required to keep your fish healthy I can guarantee that your fish will never be healthy and they will be a source of constant worry.
Bala sharks are non-aggressive. I have had several of them, and they have never tried to attack or harm the other fish in the tank.
I am hoping to get the following: - 3 bala sharks - 2 koi angel - 1 leopard-spotted plecostemus
in a tank as big as it. you'll need to check up that on google or someplace like that for the open the oacen AF
