Good recommendation...max size is 4"...is that the diameter of the fish, or the length from tip of nose to tip of tail?
These would probably work the best, but a 4" fish seems like it might fall prey to a larger fish...exe the eel or the shark. Any words of wisdom about that?
I am pretty sure a yellow ray gets bigger than 4" round. I am pretty sure I saw one down at black tip 17's that was closer to 8". I could be wrong though
