So I'm a beginner to owning Tarantulas and I own 2 as of right now but one of which I'm concerned about. I have an Aviuclaria Versicolor sling (3 months old), it has molted 1 time so far. It's been happy and healthy until maybe 2 weeks ago, i fed it 2 crickets within 4 days and I know that if you over feed them they wont eat for a while but its now been NEARLY 3 weeks and it seemed as if it prepared to molt and never did? It barely moves and just sits in the web and occasionally turns and faces a different way. My concern is that it wont eat and wont molt or even move very often, im just looking for thoughts on what the cause is and if you can tell me some of their behaviours to reassure me that nothing bad is happening, again I'm very new to this. Also my other T has molted 3 times and is extremely close to a 4th molt and is also only 3 months old.
