I am sorry to hear about your shrimp.
You may want to stay away from any more shrimp as I just read this about them.
The Bicolor Pseudochromis (also known as the Royal Dottyback) is bright purple in front, the rear half is yellow. Pseudochromis (also known as dottybacks) are among the hardiest fish available and are very easy to maintain. This little beauty can be aggressive toward other fish small mild mannered species, especially in the restricted confines of a smaller tank. Provide with plenty of suitable hiding places. Will eat very small shrimps (e.g., anemone shrimps) Provide a varied diet including meaty foods such as mysis shrimp, brine shrimp, finely chopped seafoods and frozen preparations.
