Wrasse! Thats my build thread and I got to stick with it! I would actually say anthia, but since I can have different species of wrasse that act different and not just stay in the water column, I choose wrasse!There are many different species of fish out there and we as hobbyists tend to keep a lot of different fish as well. However, what if you could only have one species of fish in your tank? What would be that one fish species you would want to have in your tank?
