Honestly IMO they probably not gonna bother anything, but what I would do is try to siphon out as many as possible when you do your next water change and feed your fish lightly for the next week or so. Help starve them out and id say they should go away without any drastic measures. If the problem keeps on after this then id look more in depth, but your tank is still new and tanks do weird stuff in their first year lolAre they bad
