Ant Farms and insects have always interested me. As a Child I would play with spiders and worms outside. Capture lighting bugs with my butterfly net in the warm summer months and release them the next morning and even bred Rollie Polies.

Uncle Milton had the first sand ant farms out there and hd live ants for sale in the back of the comic books. Sea Monkies to if i recall another company did.
Well I see there is now some interesting Gel ant farms that are different and a Unique living art in my opinion. Many colors to choose from Such as fascinations Antworks Habitat Blue or The Uncle Milton Green 3d space age gel.
