.. for some reason my two black fin sharks are laying down in the corner in the tank and it looks as if they are breathing hard and the water temp is only 84 degrees and suggestions??

Ah, the vagaries of common names!
"Columbian shark" refers to
Arius jordani (sometimes
Arius seemani) [see
this link] – a large catfish best suited to a marine setup by adulthood (gradually increase salinity as they mature; though they do well in freshwater as juveniles, they, upon having attained a length of four to five inches, do noticeably better with the addition of marine [not generic “aquarium”] salt to their water).
Not:
- The
"Bala Shark": (
Balantiocheilus melanopterus) [aka "Bala sharkminnow", "Silver shark", "Tricolor shark";
Puntius melanopterus,
Barbus melanopterus (invalid)]
- The
"Highfin Banded Shark" (
Myxoxcyprinus asiaticus) [aka "Chinese Highfin Sucker", "Sailfin Sucker", "Chinese Sucker", "Wimple Carp";
Myxocyprinus asiaticus sinensis,
Myxocyprinus asiaticus asiaticus (likely syn)] – Attains lengths approximating 40 inches in captivity (is endangered in its native China)
- The
"Iridescent Shark" (
Pangasius Hypophthalmus) [aka"Irridescent Shark" [sic], "I.D. Shark", "Siamese Shark", "Shark Catfish", "Sutchi Catfish";
Pangasius sutchi (syn)]
To see the clear distinction between the “Columbian” and “Iridescent”, look to
this link.
- The
"Rainbow Shark" (
Epalzeorhynchos Frenatum) [aka "Red Shark", "Ruby Shark", "Red-Finned Shark", "Redfin Shark";
Labeo frenatus)
- The
"Red-Tailed Black Shark" (
Epalzeorhynchus bicolor)
[aka "Red-Tailed Shark";
Labeo bicolor)
… Or any of a veritable host of dissimilar catfish, cyprinids, etc., united only in vaguely “shark-like” finnage or profile.
NOTE: As I understand it, “Columbian Shark Catfish” are relatively fine-scaled fish and, as such, have heightened sensitivity to certain medications. I would err on the side of caution with future dosing.
Questions:
- Can you describe the setup in which your “sharks” currently reside? (State volume, filtration, and any other points you feel to be pertinent.)
- What (and how many) cohabitants dwell alongside said "sharks"?
