I'm wondering what shrimps could live together in a 90g barebottom. I currently have 1 peppermint shrimp in QT w/ my convict tang, although he performed cleaning for the tang once, I haven't seen him do it again. I know that skunk/scarlet shrimp is good for cleaning parasites but I had one once that ate all the flesh off of 6 chromis. So I'm weary of the skunk/scarlet shrimp. I definitely want a blood/fire red shrimp and wonder if they are compatible with pep. shrimp and if I can have more than one. I know coral banded are popular but I've heard they aren't always reef safe, is this true?
