Phrynus Whitei Setup

[HumidElk525633]

What would the setup look like for a Nicaraguan tailless whip scorpion at 1”. Do these grow larger and how big are they fully grown with their sensory feelers fully extended out? Thinking of buying one and putting it in a 8x8x12 tarantula cribs treehouse enclosure. Is this too big? Thanks. Also any crazy humidity needs or anything?

8x8x12 (assuming inches here) is fine. It might appreciate an extra diagonal slab of cork/styrofoam/wood besides the vertical wall to feel more secure (they tend to feel more secure when they are in something like a crevice and can feel a wall opposite them). If 1” is the body size then it should be close to full size. Remember that they continue moulting for their entire lives so they need plenty of vertical space to moult in. For humidity you want to keep the substrate moist at all times and restrict the ventilation - my enclosures typically have a single 1”-2” wire mesh square as the only ventilation. They don’t care about mold, but they will desiccate if it gets too dry.

Thank You! Yes that’s in inches. I assume you mean that the substrate should clump together but not squeeze water out. One more question, is room temp fine for these? Like 68 Fahrenheit to 73? Thanks

Honestly even if the substrate gets a little extra wet sometimes the amblypygi won’t care. They don’t walk on the substrate and they don’t care if there’s a bit of mould. Too dry is dangerous. A little too wet is mostly only annoying for you.
The room temperature range you quote is okay. They are tropical animals but they prefer cool damp crevices, so as long as you’re not going lower than 68F you’re definitely fine. Mine have even been okay in 65F for a day or so during a cold snap with no issues, though I wouldn’t want them to stay at that temperature for long. They can also easily tolerate much warmer temperatures. Moisture is a much bigger factor in success with this species than temperature.

Thank you for answering! My house never gets below 68 so all good with that
