Waste or babies?

[Scma]

Earlier today I was cleaning the tank and cutting out large chunks of anthelia. During this, my dendro (which sits in front of the anthelia) looked like it was closing up, but then his mouth opened really really big and the whole thing contracted and out came a puff of whitish substance. This happened several times before he closed his mouth and opened back up again.

Have had him about 4 months now, never seen it happen before.

So, Waste or babies or none of the above?

sounds like spawning.

Thanks

I saw a couple videos, and I agree.
Should I expect anything out of this? (AKA baby dendros)

better feed a ton of photoplanktin

when this happens.. can it harm a tank? or will the spawn just disperse and eventually disappear and no damage done?
