To expand on the information already given;
The way you obtain the Goldfish item was changed in 1.2.3, an update that console hasn't got yet. You now needed to catch one using a Bug Net, instead of just killing one. Presumably to make it more like other catchable critters, left-clicking with the item selected since the change makes the player release the goldfish rather than consuming it. It also could've been changed due to the fish-farms-for-lazy-money™ everyone (and I mean everyone) made.
I expect the healing effect will be removed from console too, when 1.2.3 hits.
