Very nice puzzle. I enjoyed the symmetry.

What a lovely puzzle! Thanks very much - I really enjoyed the way all of the pairs interacted with each other.

Such a beautiful puzzle, and the interaction of the dominoes makes a very interesting solve.

First time I got to the end and the puzzle was broken in a way I couldn't solve. Came back a couple weeks later and solved in about 30 minutes. Some days you get the bear, some days the bear gets you. Thanks for the enjoyable puzzle.

Not sure where others are having the trouble, but coloring the Kropki pairs helped me a good bit with this one. Fun solve.

I am not sure why, but I really struggled with this one. I am going to have to solve it again, because there is something I must be missing (must be the but ... ;-), if it is only rated 1 star difficulty.

@ JR_Pianoman - I was coloring those and the "obvious fish".

What I was failing to do was apply all the logic from the constraints interaction, everywhere they occurred. I kept thinking things were exactly symmetrical, when they were mostly symmetrical.

Absolutely beautiful solve path. Really clean, simple setting, and it demonstrates the swordfish really well. I haven't had too much experience with swordfishes, but this made it really easy to understand for me.
