Saw Raz (betta) intently studying a spot on the wall and nipping at it occasionally. Leaned in for a closer look and saw what I thought was a little white hair. Then it moved! He managed to gobble it up in the end but do I need to worry about this thing? I searched around here and discovered it's probably a Detritus Worm. Pretty sure I have it because of all the plant die-off I've been experiencing while trying to find things that will grow in this high-flow tank. Should I just do a major vacuum and water change to get rid of the food sources?
