+2 to what happened last round.
Also, unless you are planning to add a refugium that is at least as big as your 130d, or to grow pods in a separate tank, stay away from Mandarins or you will most likely have a repeat.
My personal opinion is Mandarins and Dragonets (like scooter blennies) should be kept by experienced reef keepers that have a system that is designed specifically for them. These types of fish are specialist feeders and slow ones at that. They cannot out compete other reef fish for their food, pods....live pods. Before anyone throws it back, I realize there have been successes in getting mandarins to feed on frozen foods, but it is NOT the norm for these species. If your goal is to really keep mandarins, I would recommend working your way up to them by keeping a successful mixed reef first for a couple years. (So you can learn how to handle the emergencies as they happen) And then upgrade your system and build one specifically for them and other peaceful species. (Coral research will be important as well) Dragonets are surface swimmers they travel on the rock and sand and not typically in open water, so aggressive corals with nasty stings, anemones, etc, IMO should be out of the question for this type of tank.
