Hi all,
New one for me, they are a weird luminous green. I like them, but could imagine they aren't to every bodies taste.

Ophrydium versatile

I've learnt something new today, Ophrydium versatile is a symbiosis between a colonial ciliate and a green algae, so similar to a coral with zooxanthellae or (<"Hydra viridissima">) or a lichen etc. <"The microbial community of Ophrydium versatile colonies: endosymbionts, residents, and tenants - PubMed">*.

Ophrydium versatile is a sessile peritrichous ciliate (Kingdom Protoctista, class Oligohymenophora, order Peritrichida, suborder Sessilina) that forms green, gelatinous colonies. Chlorophyll a and b impart a green color to Ophrydium masses due to 400-500 Chlorella-like endosymbionts in each peritrich.

* for those who are interested in that sort of thing, one of the authors is, the late, <"Lynn Margulis">.

I've never heard of that before. That's a very crazy combination. But at least it looks good. 😉

the way it is attaching to the glass is giving me coralline algae or clado vibes, i wonder how easy it is to spread to other tanks once you have it..

Fantastic.

...... Ophrydium versatile is an indicator for very good water quality

I also wonder if it is another species of Ophyridium (or similar protist), purely because it seems to have a goblet shape, rather than being just a "blob".

Easily, I'm going to guess.

i also thought they were goblet shape at 1st glance, but i think it is a trick of the lens with them being transparent so the look darker where you can see they overlap?

I think you are right.
