around a week after i got my red knee tarantula, i noticed a couple of mites on my arms after taking her out of her tank. later on i transfered her into a bigger tank and these mites multiplied. i asked someone at the pet store and they told me to take her to a vet right away. when i got home i put her back into the smaller, clean tank and changed the soil from dirt to sand and she started eating again and i haven't seen the mites since. it's been a couple of weeks now, and she seems fine. but i am wondering if these mites are parasites or just scavengers. the ones i found look like fleas only smaller. if i need to take her to the vet i don't want them to tell me that there is nothing wrong and pay $54 bucks. i just moved out so i'm struggling with money not to mention my hours at work have been cut in half. after telling a veterinarian my situation, he told me it's up to me. can anyone give me some input, please? can i put the vet appointment off a couple more weeks or should i take her in right away? thank you.
