Wow. They almost look like octopus eggs. If you've ever seen a female in a den with the eggs tending them its pretty cool. Maybe some sort of other mollusk eggs? Snails or other such invert? Maybe Clown eggs as suggested by others?
Seem to be attached at one end in your video, so it would seem they were placed there individually as opposed to multiplying/splitting/spreading?
I realize now that this response was absolutely no help! LOL!
Thanks for the help guys, I don't have a Clown goby pair but I do have a few different kinds of clowns are the tomato clowns host the bta that was right next to it and probably stung it to death. what a sigh of relief they aren't aefw!
