Hello and how is Wacca doing? Although a concern to watch out for, would not stress about a Pacman not pooping for a week or so. Fresita has done that a couple times. Then she makes a mess in her bath for a few days in a row.

The CA/vitamin supplements are important to a growing juvenile. To dust with earthworms I rinse one in a little cup of dechlorinated water. Then use paper towel to dry worm a bit and sprinkle a pinch of CA on worm, then tongue feed to frog. Do that M/F and same for vitamins on W. T/T/Sat frog gets 1/2 dozen adult crickets (mine is 3 in. SVL. Sunday is off feeding day. That schedule works fine for me but you might need to adjust according to frog's response.

The shredded coco comes in loose and bricks you have to re-constitute by soaking in dechlorinated water. I prefer the loose kind; but can save a bit of $ by going with bricks in 3 packs. If so, get the Plantation Soil by ZooMed. ExoTerra's EcoEarth bricks are harder to deal with and I have found pieces of rope, wire, plastics, you name it inside them. The loose EcoEarth does not have those issues. No matter if using bricks or loose; you want to adjust water content so substrate clumps in closed fist without squeezing any water out, just slightly damp.

If buying analog gauges, do compare them at store and avoid any that get away from the average median reading. Have seen 10-20% difference in some humidity gauges at display and you do not want those stray ones. Digital gauges are more accurate but costlier too. Hope this helps and good luck !
