good choice, btw if your cabomba doesnt fit in the biube e.g. too tall you should leave it for a while before trimming the tops as when i first got them i trimmed on plant and it died from the shock, instead wait until they start sprouting white roots from along the stem, this means they have acclimatised to the tank and are starting to grow. also i would reccommend that for a while after getting the plants you set the light so that there is 14 hours of daylight, do this at 6ish in the morning by turning the light off then turning back on again a pressing the button 5 times
hope it all goes well!
