Would it be okay to keep shrimp/crayfish with these products?
Before I started keeping more plants I wasn't using any fertilizers. However before I started adding them I lost my ghost shrimp. I would like to try shrimp or crayfish. However I have been using Flourish Excel and Seachem Flourish Tabs. The Flourish Excel says safe for invertebrates however the Flourish Tabs have 0.001% copper. Would shrimp or crayfish be able to stand it? I just wanted to make sure if its okay before I order any.
Rest in peace:
