I have had skunks, fire, and peppermint shrimps in my tank. The fire shrimp had a great personality and would always put on a show at feeding time. The peppermints just stuck to being concealed and never came out. Most of the ones I have gotten have perished in the tank. My skunk that I have now, has a great personality as well. He is always active and putting on shows. He does his job rather well as I have found him eating a dead bristle worm, all kinds of dead snails, his own molts, pieces of the algea strips, mysis and brine, and whatever he find on my hands and arms when they are in the tank. I would vote for a skunk shrimp and would really suggest a pair of them.
