I want to get a possum wrasse for my 10 gallon reef. So far I have only had fish losses related to fish jumping and only one other livestock loss, an emerald crab. I have seen sources suggest possum wrasses are an "expert" fish but cannot seem to find any reason why. Would one be a good fit for a 6 month old softie reef with one shrimp goby pair, a few snails and hermit crabs, and two shrimp?
