Help in identification

[Doc_]

Hi 

 

I'm hoping someone can help me identify these critters that seem to have popped up in my tank the last day or two 

 

It looks like potentially the early stages of aphasias? 

 

The strange thing Is that I just did a tank upgrade a week ago and the two structures with the critters were in my old tank but i never ever had an aptsisia or any of whatever those are. 

 

I also haven't added anything recently other than a fish about a month ago in the old tank but that fish was acclimated and went through two baths before actually making it's way to my display.

 

Any help is greatly appreciated 😊

Early aiptasia look like aiptasia, just tiny.

 

These are pineapple sponges. They're harmless. Probably conditions changed in a way that they like.

Best news I've gotten in a week 😂

 

They looked a lot like what thus image shows as a young anemone so was very concerned and scratching my head in how 

 

Thank you very much 😊
