What Are These White Floating Things?

I switched on the lights to my shrI'm tank and it is covered in these white floaty things . I have only been away two days. I'm pretty certain it's hydra but would like clarification before I dose anything .

 

Can you get a closer pic?

Hydra are relatively large in the microscopic world so you should be able to clearly identify them by searching an on google.

 

It is the best I could get , all the white things on the glass are clear to see ? Sure I can google and I'm pretty certain it's hydra but I just wanted clarification from a pro before I dosed anything as the sensitivity of the shrimp. Thank you

 

Well I keep most aquatic cultures for study , and I’m just letting you know without a closer look I wouldn’t be able to tell you if that is in fact hydra , it’s Does kinda look like hydra shape but round and flat worms are also white and in large numbers when mating they entangle kinda like that. If it’s one solid anchor with multiple tentacles at the other end then yes it is a hydra.

 

Kind of reminds me of bryozoan colonies

Yeah could be but aren’t there only a couple of types to live in freshwater so it would be something of a miracle right? Without a closer picture of the tank it’s hard to tell.

 

I've tried getting better photos but I have shaky hands , hopefully these fair better .

 

Could it be ich ? X

 

The white spots are actually bubbles it's the tentacle things . It's mainly a shrimp tank with 3 endler livebearers (male) . No shrimp or fish deaths or illness and parameters are spot on 0-0-5

 

I’m going to have to agree with Keystone it’s probably a bryozoan colony starting to form if free swimming they could be zooids and if attached they are adults. Could be plumatella repens but I’m not 100% sure. Any way you could send me a specimen so I could observe it under the microscope?

 

Thank you , I am in the U.K. So don't know if sending a sample would be possible?
Can they harm shrimp , I'm doubtful of it as I've seen my shrimp on the glass beside them .
How do they come about to be in my aquarium .
Sorry for the questions , I have tried googling but not a lot of information out there in simple terms .

 

The eggs of many micro-animals are incredibly durable and can survive all kinds of environments until water conditions are perfect for hatching. Many can even survive being dried out for years.

Water conditions become favorable and they just seem to miraculously appear from nowhere.

 

Ahhh dang lol, well your stock should be alright if they are in fact bryozoans they are filter feeders and eat microscopic protozoans(lil animals) and free floating algae in the water column, just monitor the situation and let us know if you see anything else alarming.
