How potentialy damaging is it when a large squamosa spawns.
It probably all depends on the size of your aquarium and it's filtration, circulation, etc.
None of my critters suffered during the clam spawns I witnessed. Most reef spawning activity usually happen shortly after lights out, but I've noticed that clams and many fishes spawn in the late afternoon when the lights are still on.
I've always been lucky enough to have new water ready and fresh carbon on hand during the spawns I've witnessed, but who knows what I've missed!
During a "thick" spawn I (also) crank up the skimmer to "super wet mode" to remove as many gametes that I can possibly skim out as quickly as possible.
The spawning activity of one critter will often trigger simultaneous spawns of other critters. This is probably a greater danger.
FWIW I had a large patch of
Caulerpa go sexual on me years ago.
It stressed out my fishes pretty good (rapid breathing.) This was the single most stressful spawning related event I've ever witnessed in my aquarium.
