Tisbe biminensis are tropical sub-tropical. They are a great inoculation for your tank. They eat detritus, phyto, fish food, fish waste and multiply. We don’t worry about skimmers, pumps, uv…just add them and stand back. Of course we recommend repeated additions, but really, we are serious. Great for seahorse frye, mandarins, wrasses, invert larvae, great for reef tanks. We offer this one as AlgaGen PODS Tisbe .
