Firstly, to calm it down, just give it a bit of fish food.
Secondly, if it's wild, and it's big, then give the fish a bit of space so maybe buy him a large fish tank and some decorations for him to play with.
Thirdly, let him him have a bit of time by himself just to relax and get used to his surroundings.
I hope this info helps!
A animal that is big enough to take care of food
Most large fish are predatory; thus they usually eat smaller fish.
If you want a beautiful and colorful fish tropical. If you want graceful and big fish goldfish. But if you want a huge fish [Chicld] I do not know how to spell Chicld.
if it's big then try feeding it betta fish food. shrimp also eat phytoplankton.
as big as your imagination can take you.
The biggest size of river fish.
You could use a big beetle, but the best kind of bait would be a small fish, such as a sardine, because tuna are big fish that eat smaller fish when in the wild.
To take care of mollies you have to feed it 3 times a day and tropical fish food (breakfast, lunch, and dinner) if not done they will die. You can keep them happy by letting rome around in a big fish tank. You must put a heater in your tank are they will freeze to death. Remember a happy fish is a healthy fish.
They are the biggest fish you can find in the river (in the winter)

If you take care of little things one at a time, they can add up to big things.
You need to put it in a small tank or a big tank if you want to add more fish. put a thermomiter for the temprature. give it food at the right time. then you have a very happy fish! Make shure it has the right thing at the right time.
