Which fischeri? There are several species. Photos needed. Probably the most likely would be B. fischeri multituberculatum. Montane cooler climate, lots of water and higher humidity than veileds, panthers, or even jackson's. Sensitive to supplements, very active and can be shy. Almost all fischeri you find will be wildcaught imports so be ready to get repeated fecals and to deal with dehydration issues.
