Also, yes are absolutely massive adults planaria worms in the pics. Don’t care about risks, I only see maybe one or 2 dead shrimp each month. They’re not harming the colony. I frequently watch them feed on pellets together. Seems to be the less dangerous species. Got lucky and ended up with a perfect self sustaining ecosystem. Haven’t done a water change in 7 months. I tested my tap water for all metals and contaminants so don’t worry. I supply all essential supplements occasionally
