Any advice for someone looking to own a hamster or gerbil

Hello! My husband and I would like a pet, unfortunately our apartment does not allow cats or dogs. We were thinking of geting 2 gerbils or 2 hamsters. Does anyone have any advice on owning either of these pets, their habitats, their food, anything?

Thank you so much in advance for all of your help!

Yes I do:

First, if you want to get two of them, get two gerbils, not two hamsters. Hamsters are known for fighting more even though gerbils fight sometimes too. Gerbils should always have a friend in their cage because they get lonely. Also, hamsters are more nocturnal them gerbils. Hamsters are very lazy during the day while gerbils are up and ready to play.

Cages: You can always get those cute little tube cages they sell for pocket pets at the pet store, but personally, I don't like those. They make a lot of noise. I prefer an old fish tank (a 10g is a good size) They are cheaper too since they can't hold fish in them any more. With hamsters, you must change their fluff once a week but with gerbils you only have to change it once every three weeks.

Bedding: You can buy bedding at your pet store, Care Fresh is what I use. Also make sure you have another bedding thing in their for them to sleep in. I put old socks (clean of coarse) and towels in there for them to shred up.

Food and water: Pretty basic, a water bottle, change it every day, fill the food dish with hamster or gerbil food and refill when empty. With gerbils, don't refill the bowl until it is entirely empty. Gerbils will pick out the fattening, bad for you seeds first and not eat the healthy stuff until all the good stuff is gone. Make sure they eat ALL of the seeds in the bowl before you give them more.
