If your LR was already cured LR from the LFS, then it only takes your tank about 5 to 10 days for you tank to cycle, so your probably doing ok, just make sure you do about a 20% water change after it finishes it's cycle. If you want to get more LR, especially online LR that get's shipped to you, then don't really add anything else to your tank until you get the LR in that you want. Your tank is going to cycle again when you get a bunch of online LR since it will ship and get some die off after it is put in your tank. Your damsels will probably live through this as they are very hardy fish, but you may want to get the damsels out before you add more LR so they are easy to get out. If they are not a semi aggresive or less aggresive damsel, they will get very teritorial and make it hard for you to add any more fish into your tank. Those two damsels will pretty much attack any fish you put in there and possibly stress out, or kill them in one way or another. Those type of semi-aggresive damsels can be passive and not very aggresive, or sometimes they can be very aggresive, you just never no until you get everything in there that you want. A lot of people say, why put a $5 damsel fish in a tank with a bunch of $50 dollar fish just so see if it works, I mean why take a chance.
If you want damsels in your tank somewhere down the line, they should be the semi aggresive kind and also be the last fish you add after everyone else has established there area's.
Good Luck and welcome to the Grind!
