the tyranids have consumed over a dozen galaxies worth of bio-mass, i don't believe there's enough life in our galaxy to combat them if they arrayed their full might.

i reckon all the hive fleets that have been encountered so far are essentially the scouting party for the proper fleet which hasn't arrived here yet, and is slowly and inexorably surrounding our galaxy before chowing down :)

i also reckon the only race that could combat them effectively would be the orks because of their biology - a propensity for violence coupled with their reproduction gives them a chance to cope with attrition. however they would only stand a chance if they were completely an utterly, 100% united as a species which, lets face it, 'aint ever gonna happen :)
