congrats on a new baby!

you got great advice already, just to add. I'm always using those expandable blocks, adding as much water as i can and then squeeze all extra water to get consistency I need. I would use eco earth and not plantation soil. plantation soil has a lot of plant matter and a lot of other stuff that can cause impaction if swallowed, eco earth is more fine substrate, but still you'll need to take all bigger pieces out. you don't need to break anything, take one of the bricks put it in rubbermaid container and dump a lot of DECLORINATED water and wait for it to expand, when that happens just stir it, take pieces that might cause impaction and and you are good to go.

Crickets I prefer using yellow fluckers water cubes with Ca and fluckers cricket food. not big fan of orange cubes. it will color frogs poop for one, and i noticed that probably crickets doesn't taste ( or smell) the same and frogs not like them so much, but taking, however my cresties won't even look at those crickets. and also orange cubes are more expensive.

200 crickets for a baby pixie, hm..... i bet at least half of them will die eventually. I would suggest getting smaller amounts, 50 max for a baby and increase as it grows and what is even better switch to nightcrawlers - more nutritious, zero smell, no escapees, can stay as long you need to in a fridge and use crickets once in a blue moon for your pixie to have fun catching.

29g tank for a crickets is fine, you need to put a lot of egg cartoons in there, put a clear tape along the top on a glass. but I would say you also would need a cricket keeper exoterra or zoomed, with tubes for easier catching them when feeding. a lot of headache, right? :lol: so I'd say instead of using your 29g tank get big exo terra cricket keeper ( with 4 tubes) and put 50 crickets in there, less space, less smell, less everything
