Fluid rendering texture

[yesod30]

I was trying to make some new fluid, a water of every one of the color. I tried to use for statement, to avoid doing 16 class, one for every fluid block. It creates correctly the fluid, with different names and inventory space , but it set the texture always to the first fluid texture.

I can't understand why, since it should take different name for every time it creates the block. I also check the png name, and they are correct.
