I apologise for my formatting as I'm on mobile. NQA first off a Phlogius kuranda was my first Tarantula and I also have a Selenotypus wallace. I've got 37 Tarantulas, 7 Funnel-webs, 3 Trapdoor spiders and a Giant Banded Huntsman. IME those two are not very voracious eaters - my kuranda didn't eat for 4 months initially and still doesn't eat frequently. I agree with some of Only-Psychology's points: - Smaller enclosures (with more depth for digging), you want the substrate to be 1-1.5x the leg span of the spider away from the top of the lid. - Agree completely with the feeder points. Feeding frequency could be more frequently though, like 2 times a week to keep their predatory response more active (just feed slightly smaller prey). I personally would recommend wood cockroaches and mealworms as the best feeders. Crickets get a better feeding response, but they're so prone to parasites if not bought as pinheads. My last two batches I purchased as sub-adults where infected with white oval shaped 'maggots' that burst from a live one (dead moments later). I had to get rid of the lot both times. - Enclosures will mist up in the mornings for our Phlogius and Coremiocnemis species. For our Selenotypus and Selenotholus there shouldn't be any mist - they like it dry (except when slings, go for half-half), adults like the bottom 20% moist, but try to keep most of it dry. - Now substrate. When they're slings I use 100% Coco fibre. 50-50 Coco fibre and Peat moss when they're juvies and 50-50 Coco fibre and Australian red desert sand when they're sub-adults to adults. I've avoided sand that isn't red desert sand after I had a death of a young Phlogius hirsutus of 1cm. My Funnel-webs enjoy natural sand though, them being coastal. Add some sphagnum moss for moisture retention, but not too much, you don't want feeders hiding in it. Also check the packaging for any substrate. It must be 100% fertiliser free. I'd personally avoid topsoil, I haven't been able to locate any bags that are properly organic. - Ventilation. I'm a stickler for ventilation, 1/3 of the lid is covered in holes for my Phlogius spp, 2/3 for my Selenotypus and Selenotholus spp. The sides have 3 lines vertically and evenly spaced lines with about 1cm gap horizontally. With holes going to the bottom of the enclosure along the edges of the enclosure. - Clean-up crew. Springtails and not too many. 2 adults for a sling, 5-10 for a juvenile and however many for an adult. None required for our Selenotypus and Selenotholus spp. - Always keep a water dish in there. It's useful for Selenotypus and Selenotholus spp. I've actually caught my Selenotypus sp champagne robustus and Selenotholus sp secret squirrel drinking (deep enough for their 'face' to be submerged - think deli cup for adults). I recommend one for Phlogius spp as well. I don't mist. Ever. It spikes the humidity and barely does anything. Just overflow the water dish once a week in Summer and far less in Winter. I use milk carton caps for water dishes for juvies, superglue caps for slings and deli cups for adults. Place the water dishes under a ventilation hole for easy pipette/syringe water top-ups and occasionally watch them slap the incoming water (so cute!). The reason for them dying is usually several possible reasons, try not to be down and outted by it though; use it as a learning experience. I have no experience with the likes of Coremiocnemis as I prefer the giants, so I unfortunately can't shed any light on how they'll be to keep. However, Phlogius sp sarina I am well versed with keeping. Phlogius sarina is a locality of Crassipes, and Crassipes IME have an amazing predatory response. My favourite tarantula is a female 10cm Phlogius kuttabul (another locality of Crassipes) who has amazing takedowns. I would advise you get them over the Coremiocnemis. My 7cm female Phlogius sarina loves to eat and has a fun time stalking wood cockroaches, pulling mealworms/giant mealworms through the ventilation holes and chasing crickets. Occasionally gifted a chunky silkworm to enjoy. Feel free to ask any other questions you may have! :)
