Advertisement Bobby, I feel so sorry for your losses although it looked good since they were eating well. I have bad experience raising slings of Pisauridae as well (see the story on this topic... http://www.arachnoboards.com/ab/showthread.php?t=52860&page=2 Maybe pray variation is an issue for this specie too.... Can you give your remaining slings baby crickets? The latter have a high food value. If they survive this might prove that Pisauridae definitely need different prey to have the necessary elements for a good growth. Please keep us informed. I am fascinated by this story since I want to find a way to make sure 100% of offsprings survive.
