I had this problem to an extent still have one or two. Apistisia x works but not really kills but babies come back. I used peppermint shrimp I bought six three Months ago 4 still alive. And I have maybe one or two apistisia left in tank and I think that's because there getting used to eating food. Don't waste money on apistisia x get some peppermint shrimp dont feed tank and go from there
