No other oddballs. Just the normal fighting conch.

Possibly the easiest way to figure it out would be leaving a camera recording the tank for a while after lights out and for a while before the lights come on (or just leave it all night). That said, as I mentioned earlier, I'm leaning towards nudibranch eggs myself, but I don't think those came from a Chromodoris species (and not just because their egg ribbons are known for laying flat rather standing on one side).

For reference, the False Pyjama Nudibranch, Chromodoris annae, egg ribbons are pretty small and look like this:

Yes, definitely a good idea with camera. I will see what I can do. The eggs for the false pajama are now ruled out. These are much larger. Thanks!!

Any chance they are conch eggs? I have seen something similar in the ocean that was attributed to being conch eggs. The following picture is close to what I saw and what you seem to have.

Most conch eggs look stringy comparatively (the conch in the photo is actually a Horse Conch - massive, predatory snail), but this does raise a good question: OP, do you have tulip snails in your tank? Because, the egg case in your pics reminds of their egg cases.

Edit: just to add, tulip snails are still large and predatory, but they're way smaller even at max size than the average horse conch (and some of them don't get too large, so they'd have a much easier time hiding out in a tank).

You have solved it, banded tulip snail. I have 2, and maybe now I have more.

you have solved the mystery. Banded tulip snail - I have 2 and now I might have more. Thanks to everyone who helped!

Hooray! Please post pics of the hatch if you can.

I will see what I can get. I’m going to put them in my FOWLR tank though, they can share some clams with the puffer and marine beta
