Hi there,
Welcome to fishlore

you can go to the main index here and look up under fish species for your shark information.
Looking at your aquarium info, I see that your ten gal tank is only one day old. You have way too many fish for that size of a tank and you will have to go thru a cycle now with the fish, which will include daily water changes. Another good reading material is the information in the main page is about the
nitrogen cycle of a tank and what you should be doing.
good luck with your fish..
