They grow like weeds and can be just as annoying. If you allow it to continue as is, it will flower, develop seeds, and proceed to drop them all over the substrate, where they will then grow into more plants, in random fashion. You'll find them growing all over the place. As to length, I had them grow to the top of my 55's(18") and then all the way across the surface of the water, from on end of the tank to the other (48"). At that point I said enough was enough and first started thinning them, and eventually just pulled them out. They will cover the surface, filtering much valuable light if you allow it.
