!Bienvenidos!

That is really cool. We have some bryozoans that are pretty common in the lakes around here, but they grow as low, encrusting colonies. I have never seen a freshwater bryozoan shaped like that. How big do you think they were?

Gracias!

This seems to be a Plumatella repens (but I'm not sure) and each zooid is just 1-2mm long. There is also a little Hydra in the center of the third photo if it helps to get the size.

I hope I can get a macro lens to take a better photo of a single zooid.

You must have gotten those shots with pretty good magnification.

Where in Mexico are you?
The photo was taken with a 15 MP camera but I cropped it to get a closer look of them :).

I live in Texcoco, which is pretty close to Mexico City but I don't know where those little animals came from. I bought some wood, plants and black soil in Xochimilco, so maybe there were some statoblasts in any of those and they grew in my aquarium.

Nice

Man, I'm jealous. My goal has always been to get as much biodiversity as I possibly can in one tank. Those looks awesome! I bet this is a well established tank. Do they feed on plankton?

What cool photos!

And welcome to TPT! :)
Thanks Laura

I think I am very lucky to have them. Some time ago I read about them an I always thought that it would be awesome to have them in my own aquarium. Now that I can see them moving and growing I can say that it is a marvellous experience.

My tank is only 4 months old but I worked very hard to get it in balance since it is an "El natural" style paludarium with emerged and submerged plants, no bulbs (yes, I only use sunlight) and a lot of algae eaters :icon_bigg. I hope to take some photos of it to show you what I'm talking about.

Do they feed on plankton?
They feed on everything small enough for them: green algae, bacteria and unicellular animals. I think that because of sunlight they have enough food.

I took more photos and I've noticed that they grow very fast, compare the next photo with the second one in my first post:
