Our new 5" baby to my 4 month 13 inch baby? I know not in there vivs, due to the whole teritory thing.
When i brought the new guy home(noname yet.) I gave schnitz a quick glimps, but didnt want to stress
the little guy out. Niether bearded, waved, or anything, but after taking schnitzle to the couch, she jumped
off and ran over to the new ones tank and tried getting another peek.
I'm concerned about the size difference. Dont want schnitz to think new guy is a snack, or attack it or anything.
Should I wait a while?
You don't. They're solitary creatures. They don't need tank buddies. Plus your older one will probably get aggressive with the little one and most likely attack it, if not kill it.
Even outside of their vivs there can be problems. It would be best to wait until they are close to the same size before letting them roam together. And even then, you must keep a very close eye on them.
