Welcome to RB! You are taking your first steps on a journey with great rewards.
A 10 gallon tank is much too small for a tang. Tangs need at least 75 gallon if not larger. They can get to be as big as a football. Are you planning to use any live rock? I highly recommend it..even live sand will help with your filtration. You can acually use clownfish to cycle your tank instead of damsels. You can cycle it through with the damsels, but I would return them when you get your clownfish. I also recommend you always use RO water for your tank. If you use tap water, there is a good possibility it will contain copper; deadly to corals and invertebrates. Tap water can also add phosphates to your tank which will cause lots of algae bloom. The number one rule of marine tanks is (altogether now) be patient. Cycling your tank will take a little while. I would recommend you cycle it through with live rock (10 lbs). Then add your clown. Damels are EXTREMELY
