Is my baby Gerbil scared of my bigger Gerbil?

Not a good idea to put rodents together. They are fine as babies when you buy them in the petstore, but most hamsters and gerbils are better off separated. If you leave the smaller gerbil in the cage there is a good chance that the bigger one will kill him.

1. An adult gerbil will on average weigh 2 1/2 ounces and be approximately 4 inches from tip of nose to base of tail. Yes you have baby gerbs. 2. Just like humans aren't born knowing how to ride bicycles, gerbils are born knowing how to use a wheel. They are curious about it and may or may not learn to use it. I had only one gerbil ever who needed training since she needed exercise and just wasn't going near it. After several nights and lots of patience, she learned. 3. Here are some tips for gerbil bonding: - If they have food in their mouth or appear to be eating, leave them alone. You don't want them to view you as any kind or threat. - Try not to startle or surprise them. They are already hyper little creatures and you want them to be as calm in your presence as they are with each other. - Talk to them a lot. They recognize voices and will come to know yours quite well. They also learn commands and words really well. - Don't let anyone else hold them. You OTOH should hold them as much as possible. The more you handle them the more comfortable they will feel. They also mellow with age. - Don't force anything other than handling. When a gerbil eats out of the palm of my hand it's because he felt it was safe. They will always run away. :) Those legs were made for jumping and running. It's like having ADD - they can't stay focused long and are curious about everything. They will mellow and get tamer with age. 4. Just enjoy them! Find out what they like and don't like. Frozen cheese, tomatoes, beans. Discover their personalities. Change their toys around. Swap toys out. Carboard anything for shredding and chewing blocks because they have to keep those teeth filed down. They like toilet paper and paper towel tubes.

First off, you should NOT have just thrown them in together. Gerbils are very territorial and they will can and will fight to the death. Also, your new gerbil could ave health issues that it can pass to your older gerbil. Put the new gerbil in another tank away from your older one for at LEAST 2 weeks to make sure it has no health issues. After that, introduce them by using a split tank. Take it slowly, and read up on gerbil behavior and health. :) Here's a good site on building a split cage - http://www.egerbil.com/splittank.html

Make sure the each of their own house and their own wheel and plenty of things to to do in there like running on the wheels so they dont become agressive, and their own sand baths.
