Columbian Shark compatibilty

[Kookie Snatcha]

I have a 125 gallon brackish water aquarium and I was wondering if a columbian shark could live in it with bumblebee gobies, and 6 fiddler crabs. Yes, I am aware that the crabs need dry land. I have that covered already. Also what would be other good tank mates for the catfish?

The colombian shark is MUCH larger than those fish and may eat them
What about some mollies?You can try the shark but be aware that they get up to 10 inches

Archer fish or chromides might work.
