ok i have 2 of these sharks about ( 6 inches long ) and at the store it said emperior shark but i have been searching and came up with nothing on that name. i also cant find any pics of sharks like these.



my next question is i want to get a 200-300 gal next since these are in my 55 with a 6 inch tin foil barb, 3 inch id shark and a 5 inch common pleco.
i was thinking of getting a couple columbian sharks, a couple pictus and dropping the 7 sharks into the 200-300 gal tank and leaving the pleco and tinfoil in my 55.
i have been reading that the columbian sharks like brackish water and need a little bit of salt in the water to live or they will get a skin diesease and die... so can the id shark, pictus and the two bigger ones i have live in brackish water??
or should i try to keep the columbians in just fresh water and see what happens?
