I've got 2 stenos and will be getting 2 or 3 more very soon. Can I put the new in with the old straight away or do I need to do something to introduce them so they don't fight. I don't know if stenos are territorial or not.
When I introduced two new ones there were no problems. One was a male and within an hour he was getting up to naughty business with one of my females :lol2: Just keep an eye on them to make sure there are no problems between them but they should be okay.
