Forum:Goka the pyre of malice 3rd effect

Hi I've been playing yugi-oh for a short time and i want to ask you a particular issue about a monster card I can't understand.

It's about "Goka the pyre of malice" 3rd effect which says: "You can tribute 1 other fire monster to have this card gain 500 atk until the end phase". I wanted to ask if with this effect you can tribute more than 1 fire monster or it can only work once per turn (with only one tribute) I apologize for the lack of images or media sources.
