Okay, I have had this female ghost shrimp for maybe a month. She's crazy! Two days ago, I was changing the tank water and rearranging and felt this tiny tingly pain on my arm. And it was the psycho shrimp biting me! Even I moved my arm, she didn't let go until i pulled her off my arm! Then this morning, I found her eating my Betta's tail and she won't let go even when my Betta was wiggly vigorously! I pulled her right out of the tank and put her in quarantine. She already ate quite a bit of my Betta's tail! Proven by that red color in her stomach and my Betta's ragged tail with a few tiny teeny puncture wounds all over the tail! And Betta was only back for a day after recovering from a fungal infection and parasites! Those holes are so tiny you have to see it against the light. Then I remembered two weeks in, this shrimp ate the other ghost shrimp that I have had in the tank before her. I saw her trapped the other one in her claws and bite the other ones eye off and swallowed it. It all happened too fast, when I went in to save the victim it was too late. Back then I thought it was because the other shrimp was molting that's why psycho shrimp attacked and preyed on her. But I also remembered when I interfered, it bit my finger and wouldn't let go until I pull my hand out of the water and pulled her off. This is so strange! I thought ghost shrimp should be pretty peaceful! My Betta was scared of her and my otto especially so! I remembered one time psycho shrimp sat on Betta's head and riding around. I thought it was funny then, but now I felt so bad that I didn't realize she's bullying her tank mates! Can someone ID if it's not a ghost shrimp? It does have a blue hue and spots that differentiates herself from other ghost shrimps I have seen. It does have the orange wristbands. I have a newly set up 10 gallon tank fully cycled. This shrimp came with the green eggs and all of them hatched but died.
