Thanks OP for posting. I thought I had an account here, guess I was wrong.
I'm the one with the unidentified red claw looking shrimp. It's DEFINTELY NOT a euryrhynchus amazoniensis.
This shrimp is only about 1.25". Based on the research I've done & the other person that's knowledable about these critters, it's most likely a red claw variant from Asia.
Please post a link to any shrimp that you think it actually matches because I can pick out obvious differences in every picture I've seen.
