Cool FW Shrimps

Personal correspondence with Mustafa indicates the "red point" is probably M. brasiliense, the "shrimp transparente" most likely a Palaemonetes sp., and the "zebra" (as determined by images sent from Peru) most likely not a Macrobrachium at all, but rather Euryrhynchus amazoniensis, "a very small species...about 2.5-3 cm".

It is likely that the milky coloration of the E. amazoniensis depicted above is indicative of stress. Look to http://www.akwaria.pl/krewetki/alpheus_cyanoteles.html for naturally colored - albeit mislabeled - specimens.
Further Notes: Said species are all plant-safe, and furthermore characterized by abbreviated larval development.
Images:
- Macrobrachium brasiliense ("Red Point")
- M. brasiliense ("Red Point" - much more colorful specimens), with commentary
- Palaemonetes sp. ("Shrimp Transparente")
- Euryrhynchus amazoniensis("Zebra"?)

Hello everyone. First time posting here. I would just like to comment on the "ghost-type" shrimp from the Amazon region. These shrimp are most likely a Macrobrachium of some type. Most of the shrimp in this genus are piscivorous at worst and fish mutilators at best. I have had two species of the "ghost types", both Macrobrachium, and both proved to be incompatable with fish (which is why I no longer deal with them). I did also get a Palaeomonetes (identification uncertain) which looked harmless but ended up being able to capture and eat smallish fish. They are best kept in a species tank with plenty of hiding places and visual barriers so they can't see each other too often.
As to the red shrimp and the green shrimp from the Amazon....first time I have seen pics of them. VERY nice. The Euryrhynchus could probably do some damage to smaller fish, judging by the claws. I wonder if it is a fish mutilator?
Here's a link to an article on fish mutilation by M. olfersi in Brasil.

IME with other species from So. America, this behaviour is not restricted to M. olfersi.

Not unusual for most shrimp species. After all, they are prey items to most other fishes (and even other shrimp). IME, much of the damage occurs at night, when the fish are sleeping and the shrimp are out and about. But still, these are some wonderful looking critters, and are worth trying. Are these species often imported?
