I'm interested in getting something that can tame the planaria in my tank. I used no planera. I even stop feeding for a week. In my shrimp tank that I have about 2 dozen shrimp babies in. But I have planaria to there not that bad now still they are in there.. And I need a fish, Kuhli Loaches, or Bristlenose Pleco. In my tank to help eat them but not my babies. If anyone have any clue what is safe in my shrimp tank with dozens of baby shrimp. Please let me know... Thank you
