Cool thing in my aquarium

[PlantedGourami]

I have some freshwater bryozoan in my tank (photo is relatively old, from April) and thought it would be interesting to show a picture of them
They seem to grow relatively slow even with high amounts of particles in the water but stay alive fine with completely clear water and lower flow
They grow on my tank walls mostly

Very cool! That's a good picture too. How long have these been in your tank?

I've had a couple of colonies appear in my tanks too, but, unfortunately, they never persisted for more than 6 months or so.

Had them since April when I first noticed them
They seem to still be doing well (they always have the little fans out) though I did tend to have a lot of floating particles from overfeeding so maybe I might accidentally slow them down because I'm feeding a lot less to prevent water quality dips

Oh wow, I never heard of these. How cool.
I did a search on the forum, they're mentioned several times.

Here's some more photos of it
The first one is on a leafless anubias rhizome root system I have and the second is a bad photo of it on the tank wall
