jnettop

Well, it has "top" in the name. ^__~ I would say that jnettop is more similar to nethogs than htop...

I know iotop exists, but I've never used it.

htop can do all (most?) of what iotop can.

Press S in htop and you can select to show i/o-related data, including number of bytes and number of operations in total and per second.

You will need to be root to look at most i/o related data.
