Good Evening

Has anyone heard of " Peru Zebra Shrimp" , "Euryhynchus Amazoniensis" ?

I have seen them on Aqua bid a couple of times.

Does anyone have any information on them ?

Yes, I identified those shrimp for Mike who sells them now on Aquabid. They are a palaemonid shrimp, i.e. in the same group as Macrobrachium and Palaemonetes but a different branch from both. I will probably put up a species description soon for those guys. They have only been around for a year or so worldwide...so they are relatively new to the hobby. Whoever gets them should try to breed and distribute them instead of just having them as "strange" additions to their community tanks.

Do you know which type of larval developement these go through? If these shrimp develope fully in freshwater I may try them.

They have large eggs and reproduce in freshwater. They should either produce very advanced larvae that turn into postlarvae (i.e. mini shrimp) within a day or so or they produce already fully developed young. Either way it won't make a difference to the hobbyist since very advanced stage larvae are "sitting larvae" (as opposed to floating) and don't need to be fed.

Any recommendation on water parameters? Soft, hard, alkaline, acidic? Temperature? I should have asked in my prior post, but just thought of it now. Thanks.

Thank You

I Thought they were very interesting.

Mike said they were from Peru and most likely were softer water.
Not set up for soft water as of yet. Will have to wait awhile for those guys.

Yes, they are most likely coming from soft, acidid waters although there are also some rivers that have slightly alkaline water in the amazon basin. So, a good way to start with them would be to keep them at around neutral ph first and go from there. The temeperature should probably be in the upper 70s to lower 80s.

Any idea how agressive these are and if they could live with other shrimp without eating them?

big claws = potential for aggression. They should be comparable to Macrobrachium of the same size.

Thanks for the replies.

This is alot of helpful information.
