I finished up their temp tank last night. 24x18x18 Exo-terra.
Shallow tray with treated tap water, blackwater extract, some Java moss and duck weed. I have a hanging Exo-terra fake plant in anchored to the glass and the bottom submerged in the water to act like a ramp. I also have a fake broad leaf plant in the water as another option.
The substrate is made up of hydro-balls, coco bedding, ABG mix (with springtails), moss and topped with leaf litter. Some real branches make up a network of climbing apparatuses. I left the glass walls bare to give these guys a lot of options to rest on. A very shallow dish of treated tap water is there for drinking. When all tads emerge, I will replace their makeshift pond with a shallow glass feeding tray. I will keep the pinheads in there as well as release some in the environment for hunting purposes.
