Does this have a shelf life?

I've had this bottle for about 1.5 yrs. and I'm wondering if there is a shelf life on it? The bottle says store at room temperature, no need to refrigerate.

TLC bacteria for saltwater tanks. Its used for cycling and it says when you add a new fish.

Only pic I could find..

It should say on the bottle (although I just looked at the label online and did not see it). I had a bottle of bacteria starter before and it said on the label "can be stored for 6 months" or however long it was.

It most likely does have a shelf life since it is live bacteria, and after 1 1/2 years I would assume that life is near it end, if not already ended.

I've read the whole bottle several times and can't find anything... not on top, bottom, under the lid.. :lmao:

Yeah, probably should just get a new one.
