My LFS employee said that live plants can lose their leaves. My new plants sometimes do that. He said that it will regrow its leaves. Why do they do that and when will it grow back?

What kind of plant is it?  It's common for some plants, like Hornwort, to shed some leaves upon entry to a new tank and ...my cories are schooling!!!!  Yes!! 

...Sorry, it's just that two of them have been excluding the other one recently and I just saw them together...Let's move on, shall we?  :)

Anyway, some plants will drop leaves as they acclimate and may shed old leaves over time.  Older leaves aren't as efficient as new ones.  Instead of thinking of the leaves as like an arm or a leg, which we definitely wouldn't want to lose and would not do well without, think of leaves as machine parts instead.  When one gets old and squeaky, the whole machine can be improved by taking out the bad or old part and putting in a new one.

Plants do this by letting old leaves die and drop off and then growing in fresh leaves that can photosynthesize better.  It improves the whole plant to get rid of those old leaves, which were a drag on the whole system.  You see this a lot in "leafy" plants like amazon swords and crypts - old growth makes way for new. 

But some plants don't drop old leaves regularly, so we'll need to know what plant is doing the shedding.  Depending on species, too much leaf loss can be a sign that the plant doesn't like something about your water quality and is starting to die.  So can you ID your green friend?  Or find its pictures online?

And as long as new growth is coming in, I wouldn't worry about your plant losing some leaves.  It means the plant as a whole is developing and growing.

When I first set up my tank, I had some Ludwigia Repens that I planted that lost a lot of leaves. I was bummed. New ones later grew back. Evidently, Ludwigia doesn't move well and thus the cause of the leaves falling off. New tank/plants moved from store to home. I also understand that some crypts have major leaf loss when moved.

Nikita is spot on when it comes to identifing what you are working with. That would clue us in on some possibilities.

It's very common for plants to shed or melt when introduced to a new tank. It's the plants way of adjusting to it's new environment. New lighting, substrate, Co2, GH/KH.. etc might all be new to it. Once the plant settles in normally it bounces back with in a week or two. Dead leaves are a good sign if there are new ones growing at the same time.

Does the temple plant from google look like yours?

Here's what www.plantgeek.net said: Hygrophila corymbosa v. 'Stricta'

Well, it's doesn't look too different from yours.

Try and compare. Does it have the same stem structure? leaves? color (maybe not as close)?

The way I can definitely tell: grow it emersed. Somewhere that the sunlight completely batters. Let it grow in a little tub of dechlorinated and fertilized water. Then, see if it becomes covered in indigo/blue/purple flowers. If so, it's definitely that plant.
