Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 Tuner + 1+ non-Tuner monsters If this card is Synchro Summoned: You can banish 1 Level 6 or lower Fish monster from your Deck. If this card is sent to the GY as Synchro Material: You can target 1 Fish monster in your GY; banish that target, then you can add 1 Fish monster with an equal or lower Level from your Deck to your hand. You can only use each effect of "Arionpos, Serpent of the Ghoti" once per turn.
