Go with any of the Lugubris group pikes, try to stay away from cincta though as they genearlly are too aggressive. Marmorata, lenticulata, sp. 'venezuela', tapajos red, sp. 'cobra' are a few that have worked out before...but not the limitin pikes. Johanna would even work. Main thing is to stick with Lugubris group pikes and stay away from Saxatilis..as they will stay a good bit smaller.
