The Mexican tarantula species in the above photo looks extremely similar to the Costa Rican tiger rump (Cyclosternum fasciatum) but it's most likely a different species.
I keep two juveniles of this tarantula species in a terrarium with a glass divider in the middle so each spider has its own section. I feed them crickets (field crickets, house crickets) and "superworms". The latter are actually larvae of the darkling beetle, species Zophobas morio.
