I have a lightning Maroon Clown in my 180 for about a year, and when I tried to add another one the other day, the chase was on. The newbie got chased like there's no tomorrow. But I was able to net them both out and got them into a 5 gallon bucket, they been in there for about 2 days now, no fighting no chasing, swam next to each other without any fuss. How long should I keep them in the bucket before I put them back into the 180.
