Why the Pisces doesnt need water to be summoned but Aquarius need it. Sure she is a mermaid but she can levitate and Pisces can also levitate while in fish form and the fact everybody knows about fish is that live on water. Maybe water weakness was just that Lucy didnt always summon her all the time but all her fights takes place in near of water like oceans, rivers, lakes, pounds and Juvia´s body. That isnt true water and sand makes a good combination, plus almost everything can work together well, if water stream is strong and fast will make the sand like tiny bullets.
