That's unusual... do you get a lot of algae throughout the tank? Or just on the shell of the shrimps?
Hi all,
I have started keeping shrimps since last year, from tiger, bee, yamato, blue, cherry, sakura, and recently, crystal shrimps.
I noticed that once in a while, some of my shrimps, especially the cherry/sakura ones, would have some green growth on their shell. The green stuffs looked like algae, but doesn't seem to harm the shrimps. I've seen the green stuffs came off when the shrimps shred their shells. On a few occasions, I moved the affected shrimps to another tank, and other shrimps would try to help it "clean off" the green stuffs. So far, none of the shrimps have died from having the green stuffs.
Just wondering, could shrimps have algae growth on their shell, and what causes that? Can't seem to find any clues from internet search.
TIA!~

never come across a case like this, your tank must have a serious algae infection problem.
have any pictures to share?
No worries, some shrimps have learnt the art of "ta bao", food on the go helps when you are constantly engage in........
Agree, a photo shot will be nice.
That is algae growth on the glass, as well as on the rocks in the tank. But I wouldn't consider it serious kind of growth. I'm using a 42cm tank, with a 11W PL light. No CO2.
Will try to take some pictures to show. Some of the shrimps have algae on the tail part, some have more patches.
? 11w on a 42cm tank ? i am guessing you have > 7g of water, should be considered low light but having algae growth. Kinda odd, is your tank next to the window?
for me, algae doesn't grow on my shrimps, but instead they grow on the shells of my snails...
interesting to see little lumps of green things moving on the walls... hehe
Yeah, the light should be considered low for such a setup. What is "> 7g of water"? My tank is in the office, no chance of getting sunlight. Apart from shrimps, I have a few oto's, hara-hara's, and drawf cories

A clearer picture, the "algae" are at the head of the cherry, and the tail of the tiger shrimp.
It was pretty easy to get the shrimps out, they'd voluntarily walk over into the net that I used.
I've put them into a white KFC tub to isolate and get a clean background for the photoshoot. Sorry for the poor white balance, the P&S was tricked by the lighting.
The green stuffs are circled in black in the edited picture.
could it be some form of disease ie. fungal growth?
Not sure. Any ways to prevent this fungus growth?
I was pretty sure it was algae growth. In fact, one of the shrimps had shred its shell (with algae) recently. Was wondering can do a lab test or not??
Could it be shrimp disease?

Looks like water mould to me

Thanks for pointing to the website. The infection doesn't look very similar to any of the diseases listed, but guess I'd better quarantine the infected shrimps and change water more frequently.
Updated, found another cherry with an algae-head. Pictures are cropped. No resizing done.
can u share wats ur lighting regime?
as well as if your tank is situated next to places with direct sunlight?

I'm only using a 11W PL light, in a ~42cm tank.
The tank is placed in the office cubicle, no sunlight at all.
Edit: Forgot to add, light is turned on about 10hours daily.
