I have a 10" jag that now feels that my 10" RTC is a threat. The jag has been nipping at his fins all day and it is really stressing the RTC out. They have calmed downed, but every once in a while the jag comes by and messes with him. My question is should I move the RTC to an empty 45 gallon overnight to let him mend? Or should I keep him in 120 gallon because the transfer to the other tank might increase his stress? This is the first issue I've had with the jag. I am not sure what to do. Any help is appreciated.
