If you have a good waterbottle, you should only have to change the water about once a week. Water bowls are messy and don't work well. Just make sure your gerbils always have fresh water available! :-)
Hope I helped!
Just once a day. They need fresh water every day. How would you feel if you had to drink the same water for a week?!?!
those answers were stupid I'll tell you the right one cuz i just know. You should chagne water is "hi" "hi" "how are you"? "good how are you"? "im good thanks" "your welcome how are things"? "really great i just got a pet. do you want to know what it is"? "sure" "it is a dinosaur" "really omg that's so awesome" "i know". see that's just what you do. YEEEEEEEEEEEEEEEEEEEEEEEEEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!!!!!!!!
once a month at least
Every Week
You should fill it's bowl just to cover the bottom but if your gerbil needs more give it more.
Answer: I would say around 3 times per 2 months, and if that is too many, breed as much as you can fill!
EVERY DAY
You should change your dog's drinking water a couple of times daily
only once usually one-two table spoons depending on how many gerbils you have.
once a year
It depends on the type of fish.Some fishes are sensitive to water but if it's a regular fish you would change it about 1-2 times a week
Once every 1 or 2 weeks i have one =)
it has 3 or 4
No. You can have as many as you want.
