Starfish frenzy

My nitrates were at 100 so I did a 25 g water change on a 75 g tank. The starfish went crazy. They all came out and started squirting white stuff into the tank! Should I be worried?

Looks like they had an orgy

I'm guessing that the water temperature of the 25 gallons did not match the tank water? Those bristle stars will have mass spawning events and one of the easiest triggers is a sudden change in water temperature.

Can I have too many? There seems to be a lot after seeing them all out of the rock.
