dawn Posted February 23 Report Share Posted February 23 Can someone please tell me what these are in my shrimp tank. I had to redo my tank recently due to scud over population. I redid with all new products, except for my shrimp and snails and now I am seeing these. Are the scuds again and if so how/where do they come from...again all new tanks from bottom up? Attached is my before and after to show I removed all. Quote Link to comment Share on other sites More sharing options...
