So I'm currently running a 90 gallon with taotronics LED's and a HOB remora skimmer, though I'm working on upgrading to a six foot tank with a 55 g sump and thinking about going with a bubblemagus skimmer. As for freshwater I sold my goldfish, but I still have a betta tank, and I have a horse trough with goldfish in the greenhouse. I had originally bought my 90 gallon setup with the intent of moving my FW angels into the 90 and getting discus and using my 55 as a saltwater tank but it came with a sailfin tang and a foxface and once I got them home I fell in love with them and didn't want to trade them to the LFS and knew I couldn't put them in a 55 so I sold the angels and decided to go big or go home with the reef tank.
