Tips for golfing in Jellyfish
Use functions before consumed by operators

When calculating the Catalan number, I used this trick in my Jellyfish answer:

p
%C+
 &amp;
&gt;+i


The &gt; function is taking + as argument, while the &amp; takes the same + as functional argument.

As a result, the + that the &gt; gets is unary, while the &amp; makes + binary to be used by C.
