Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn: You can discard 1 card; Special Summon as many Level 4 or lower Fish monsters as possible from your Deck, but they cannot declare an attack and their effects are negated. When a card or effect is activated that targets this card on the field (Quick Effect): You can Tribute 1 other Fish monster; negate that effect, and if you do, destroy that card.
