Tbh my Coral/Marbled Cat sharks were in my 180 gallon and if I did Cat sharks again the aquarium would be 3 ft. in width. I would not recommend keeping a Cat shark in a 4 ft. aquarium.
Yeah,I'm pretty much against keeping sharks with any other fish, especially triggers.
Interesting that the guy chose to focus the camera on his face while he spoke the entire time of the video rather than on his tanks or his sharks that he spoke of.
