um in my 15 gallon tank with my pair of apistos i have noticed little worm like things that sorta wiggle in the watter. they are white and the largest ive seen in the water is about a half inch. they are white and really are interesting to watch wiggle through the water but im wondering 1)what might they be 2)are the harmfull and 3) wat should i do about them? they seem to actually be out in the water when i disturb my wisteria or gravel when cleaning. and i usually net them out when i see them but they sometimes slip through the net (just to give an idea on how thin they are) ive seen my female apisto even eat one and was at first worried but her and my male are perfectly healthy. thanks in advance
