RTC's are funny when it comes to their terrirories... I have personally done this when I had a problem with my RTC attacking another tankmate... When I changed their tanks I took out the abused fish (a smaller TSN) and put it into the new tank first and let it take over the tank for a week so it felt more confident. When i introduced the RTC into the new tank it was like night an day from before and became WAY Less agressive and moved for the Smaller TSN... I have never had a problem with them since (It wasn't a space issue either cause I actually down graded their tank from a 300 to a 270) Simply that The RTC was the first one in the Original tank and felt that everyone else was an intruder... now he is the intruder and is being "allowed" to stay.
Not saying that it works for EVERYFISH but it has worked for me...
I got 170G aquarium and i got one RTC in it 40cm and two small fire eels about 6" and some times they share same hiding spot

my RTC wont hurt a fly.

really,he is a most peaceful RTC ever.
