Hi Folks,
This female (I think) Amano has a dark sack beneath her abdomen, it gets flicked a lot. I’ve seen egg masses before but not this irregular sack shape; it has the look of something unhealthy but hopefully I’m wrong. She is otherwise behaving normally. What do you reckon?

If you have a hospital tank, or just another tank that has no shrimps in it, I would separate her in case it's something that could spread to your other shrimps.
I know that parasitic barnacles can mimic the eggs mass of a crab, and wondered if there are similar ones that attack shrimps; a quick look suggests that there are, but I haven't seen one that looks quite like the 'growth' in your pic.
You could Google 'parasitic barnacle' and see what you think.

Thanks Guys, shrimp had not really moved since yesterday and was clearly unwell so I took the decision to euthanase it. I’m away from home for a while from tomorrow and wanted to reduce the probability of whatever it was spreading to the other shrimps in the tank. I have Amano, Bamboo and RCS. Hoping this is an isolated case of infection.
