5-Link Oddagon(9):r3c39,r4c3,r6c19
Guardians(g) => -9r3c9

Code: Select all: 9r4c1 - r4c3 = r3c3 - 9r3c9; 9r248c9 - 9r3c9; 9r6c7 - r8c7 = r8c9 - 9r3c9; stte

OR:
I think this also works using the same 9s grid and two remote fins...
1-Fish r6\c9 + rfr6c17 => -9r3c9
Remote fins:

Code: Select all: r6c1 - r4c3 = r3c3 - r3c9; r6c7 - r8c7 = r8c9 - r3c9; stte

Added 1-Fish markup in hidden text:
