well today i was watering all my T's and cleaning up poo/bolus when i noticed some really tiny brownish things crawling around in 1 of the enclosures. ive never had this prob before so im going to change out the sub in that enclosure. my question is, does anyone know what these brownish things are? i did notice the other day 1 tiny fly near the plant in that enclosure but didnt get a good look at it since it was so small. now i noticed these little buggers crawling around. to be safe, would it be wise to change all my T's substrate? i have 1 currently on its back molting so obviously she will have to wait for a sub change though. in case you are wondering, its in a rose hair enclosure. pretty much bone dry with the exception of the occasional moist area when i water the pothos plant about 1 time a week. any thoughts are greatly appreciated!
