what all need to be in Columbian Sharks tank?

Question

im thinking of buying atleast 3 and was wondering what do they tank so TELL ME EVERYTHING EVERY INCH and lol this may be retarded do u like just add the salt like that people put on food in the tank and then itll be saltwater

Answer 1

The salt should be marine salt, like the kind used for saltwater tanks. As adults, Colombian sharms are marine fish. Rather than pour it in the tank, it's better to mix it up to the salinity they need in a separate containr, then add that whenever you do a water change. To top off the tank from evaporation, just use freshwater (tap water with dechlorinator), since salt doesn't evaporate.

Be aware that these sharks will be territorial as they get older and shouldn't be kept in the same tank. See the links below for more on their care:

Answer 2
