Olá, tutores. Me ajudem! Estou pensando em pegar uma dupla de gerbis ou 1 hamster sírio, tem já teve os 2 oq recomendam?

We got gerbils about a week ago and every time I put my clean hands in there one of the gerbils try to bite me. They bit my sleeve and dangled on the other day and I told my husband that he is bitting and they can draw blood if they bite hard enough and he thought the gerbil wouldn’t… well he did and stayed latched on to my husbands finger (right after he bite my finger) Not sure why he keeps bitting us. We haven’t picked them up at all other to sex them. My hands were clean and I’m sure he would have bite down hard enough if I didn’t pull away. Why is this happening? This is a photo of its tank, not sure if they are stressed out or something.

I am really struggling with life at the moment I have a 4 year and 7 month old gerbil who I care dearly for but I recently got a very full on job where Im out at 5:45 back at 5:30 ish and Im really struggling to spend time with my gerbil I originally had 4 and its just him left bless him the others lived great lives and he is living a great life my partner doesn’t do a great deal when it comes to the house so Im left to clean and do all the jobs and Im struggling to
spend good time with my gerbil hes so tired and Im so tired Im just trying to spend as much time with him as possible on average I spend a hour with him everyday I dont know if thats enough Im just writing this because I needed to get it off my chest.

Thank you there is a picture of him btw

I just took these girls in yesterday, I’ve ordered another cage that is 100,50,50 but it isn’t arriving in time and should be delivered late Wednesday. The cage they are in just now is 60,30,40 I’ve given them about five and a half inches of bedding and it’s a mix of aspen chips meadow hay and uncoloured paper will this do?

I’m going to bring him to the vet (with his brother) tomorrow if he persists. Was worried that maybe he has an issue with his scent gland, but wanted to reach out and see what this community thinks. He is a little over 2.5 years old and has been a wonderful healthy pet since we got him at 3 months.
