I suspect you mean a single fish for all three eliminations, but don't even see one for just two eliminations. However, there are two grouped finned x-wings (aka grouped turbot fish, 2-string kites) and a finned swordfish (aka grouped x-cycle length=7).

Thanks, Danny and Ron. Those finned big fish are really hard to spot.
btw, only the ER or finned x-wing for r6c4 was needed here. So it can be solved with basics, (advanced) coloring and finned x-wing.

Eh? [r9c7]-5-[r7c56..]:?: [r7c56..]-2-[r8c7]:?:

Care to explain? Or have I missed some new hyperlink you have invented?

Obviously (in the Carcul sense) the hyperlink uses the UR Type 4 in r27c56 and the ALS in r7c5689.

1. r3c7=4, otherwise the puzzle would have two solutions.

2. [r3c3](-1-[r78c3])-1-[r4c3](=1=[r4c7]-1-[r1c7])(-7-[r7c3])-7-[r9c3]=7=[r9c5]-7-[r7c46]-5,9-[(r7c3)]-3-[r8c3]=3|1=[r8c8]-1-[r1c8]=1=[r1c2]-1-[r3c3], => r3c3<>1 and the puzzle is solved.
