IAL is great, I doubt you'll have issue.
And woo, I hope you can find a few, theyre great. If they like where they live, they sprout babies under their leaves, which you can then take off and place in the tank. It takes a while, but theyre cute.
If youre going to add them, I suggest a liquid fertilizer, which will help keep them lush and pretty. Picking up a small amount of unscented epsom salt also helps in their growth- the magnesium sulfate gives a boost. I add like .5tsp/gallon (if that, lol) every couple of larger water changes.
