Is this a good setup? Constructive criticism welcome!

One female mouse, yes ik they shouldn’t live alone but she had a traumatic experience and has since become aggressive towards other mice. I tried bonding her 4 diff times with 6 different mice, nothing worked and she seems a lot happier alone (not hiding constantly and finally making nests/gaining weight).

No water bottle in this photo bc this was right after I cleaned the tank. Also the fabric on the outside of the tank was wrapped around 3 sides but it keeps falling down lol.

The tank size is a 50gal tank 36”L 18”W and 18”H, the bedding is about 7” deep.
The wheel is a 9” silent runner. The woods in the tank are mopani wood, cork logs, cholla wood, and apple wood sticks. Substrates are aspen, paper, Timothy hay, and dry sphagnum moss. Those rocks are ones I grabbed from my backyard, I cleaned them real well ofc. There are different sprays in there and she eats Mazuri mouse pellets + gets a seed mix sprinkled around the cage.

Edit: the white thing in the 2nd photo is a PVC tube I’m using as a tunnel.

Gerbil lunging and attacking me.

So I have a trio of male gerbils named Credit, Debit, and Ledger. I’ve had them since November 2025, recently Ledger had surgery for a scent gland tumor/mass and now Debit is lunging and attacking me when I try to scoop up Ledger for his twice daily medications. Right now he’s only bit me once. How I catch Ledger for his meds is I scratch the opposite side of the cage and Debit runs that way then I scoop up Ledger quickly but carefully. I’ve tried to offer treats and my hand to Debit but he just bites me. Before all this Debit was a very nice gerbil, he would nicely take treats from my hand and if he didn’t want to be held he’d gently nibble my hand (didn’t hurt me) and I’d put him back.

I know Debit is just protecting Ledger but is there anyway I can get him to trust me again? Should I wait until Ledger is fully healed to try to get Debit to bond with me again? Idk what to do he was such a lovely gerbil, I still love him and find it kinda funny when he jumps/lunges at me but I feel like it’s stressing him out.

Edit: the gerbils get along great and show zero signs of de clanning

Possible tumor, surgery vs euthanasia?

Pictured is one of his brothers.

My gerbil is an adult but I do not know his age, I got him and his brothers as adults.
They’re a trio (yes ik that’s not great I didn’t know when I got them, I’m monitoring them closely for issues) so far they are doing great and groom each other and sleep together and no bickering or fighting.

I took my gerbils to the vet within the past week because I noticed what I thought was a wound on one their scent glands. The vet is treating it as an infection for now, if it doesn’t clear up when the treatments are over then it’s a tumor/mass. Currently he’s on oral antibiotics and a cream I put onto the affected area 2x daily, he doesn’t mind and he’s very good for the treatments.

I’m debating whether to go through with the surgery if it turns out to be a mass, because I do not know how old he is. He is 70 grams (not underweight) he’s just small in stature as are his brothers. I really can’t afford the $$$ for the surgery, and with the possibility he won’t even make it through the surgery I don’t think I want to do it. If I were going to do the surgery they would have to remove the whole scent gland because I will not let them just remove the mass because of the chance it would come back.

I feel bad that I’m leaning more towards euthanasia, of course I would let him live until it became an issue because right now it’s about the size of 2 grains of rice side by side, it’s not bothering him any. He doesn’t bite or pick at it any nor do his brothers, I’ve dealt with masses in an elder guinea pig before and I had to have her euthanized because she was old and wouldn’t make it through the surgery. I just don’t know how old my gerbils are.

Is it wrong to euthanize him rather than do the surgery?

Volume all the way up to hear her crunching! 🥰

Btw the squeaks in the background are my guinea pigs lol.

I have a group of 6 female mice 2 are the same age (7 months), 3 are younger and one’s age is unknown, they’re all adults though. The 2 that are the same age are from the same litter, I also have 2 of their other sisters in a different cage. These 4 littermates went through a very traumatic event, their sliding cage door got left open on accident and a cat got into their cage and stole one of their friends. The 2 that live alone are traumatized and only accept each other (very aggressive towards every other mouse). Now back to the 2 that live in the group with the other 4 mice, one of those two is being aggressive towards one of her cage mates (chasing and biting scabs on the victim) she ONLY goes after one single mouse though, she looks just like her too. The aggressor has been moved to her own cage for a week to cool down. This is the 3rd time I’ll be reintroducing her to a group of mice, I’m at my wits end. She is also very wheel aggressive, even if I have 1 wheel for every mouse if she sees a mouse on a wheel she’ll bite and chase them off of it and then run on that wheel. If she’s on her own wheel and sees another mouse on another wheel she’ll get off of her wheel and do the same thing over and over until I remove the wheels. Yes I introduced them properly, I did a lot of research beforehand. I’m worried she’ll have to live alone, Does anyone have experience with traumatized mice? What can I do to help her? Is it at all possible she could live with others? I really don’t know what else to do :(
