Why outside my stones?

[peppe_67]

This evening I noticed that many of my brittle sea stars has left the inside of my stones and are now crawling around on the outside. Can anyone tell me why they done that?
What I changed in the latest is getting a Centropyge bispinosa (on Thursday) and started dosing with Triton core7 yesterday.

What stones do you have in your tank ??

Could be a spawning event or negative reaction to the dosing.

As the lights went down they crawled back in again only waving their tentacles out through the holes in the rocks as they usually do. They are still alive anyway so should I only let it be and give it some time?

It’s normal, sometimes the cone out to scavenge, or find another thinned leg babe to populate with.

Yup just let it be...

Yup just let it be...

Yesterday all was back to normal again, everyone was dwelling inside the rocks and let their tentacles reach out [emoji4]
