I think this is a VERY neat looking fish and wonder if it would fit well with my tank or tetras, corys, and a dwarf gourami?

Ah! Glass fish, they are pretty neat, if you have the tank space for min of 6 I would go for it, they love company with one another
They are cool looking fish.
But they dont doo much...haha
I dont have them, my stores carry them.
They just all group up, and point to one direction and stays in place.
My guess is to feed them after you turn off the lights.
