I'm extremely new to taking care of a T, and I just got my Avicularia Versicolor a few day's ago at Petco. He was fairly big when I got him, and the lady said he had already gone through his first molt, but he is still a little small. I didn't know anything really, and I found out neither do the staff at my local Petco at least when it come's to T's. I originally went to Petco the day before I bought the T to look at them, and the lady I met the first time seemed to know more, but when I went back the next day to buy my T she wasn't there. I picked up a pet keeper that would be more for a terrestrial T, and I asked the lady who was helping me if he would need a taller habitat or a longer one and she said the one I picked up would be okay. I didn't know until afterward that he was an arboreal specie's, and needed a taller habitat. He is really smart though, and actually pulled the fake plant I put in the pet keeper from his original tarantula hut up higher in the corner for support using web from where it was on the ground and he built a nice looking web around it stretching up the corner. I've been trying my best misting his habitat daily to keep humidity up, and I bought a heating pad attaching it to the bottom of the pet keeper. It's normally hot and humid here in FL, but in winter like it is now it can go from the mid 80's to high 90's all the way down to the 40's at night when winter really set's in. To be completely honest as well I'm kind of on the poor side, and the place where I live is infested with critter's like the possum's that come in through the hole's, and lizards as well as insect's like roaches. I tried to keep the roaches away, but they get into everything, and he was eating like a buffet for the first couple of days. His abdomen has gotten really plump as well, which is cute sense he's still small. lol This is the third day he hasn't eaten though, and by the time I got to town today Petco was closed so I tried getting worms from Walmart. He wouldn't eat it though, and actually ran. He seems allot less active as well. I hope he's alright, and I just hope to see him grown up when he turns those bright vibrant beautiful color's. Thank you for reading, and I hope to get some advice or opinion's. Thanks again. Also, I hope it's okay but I included a video I did when I first got him for reference.
