WELCOME TO AA!!!
Any chance you can take those damsels back, until the cycle is complete?
I would like to add a bubble anemony
Those guys need a mature tank, some say 6-12 months before adding one. They are sensitive to poor water conditions and if stressed, can die and fould up a tank.
Steve is right, tangs need a bigger tank for swimming room.
But before I do this should I have more filtration?
Biofiltration can be accompolished by adding 1.5-2LBs of LR
If you are going FOWLR
, you can get away without the skimmer.
You'll need one or two phs for water movement, test kit, heater, thermometer, refractometer or hydrometer, to test salinity. The refracto is a better tool.
You might think about setting up a QT, in the near future.
