Hi, my friend was breaking down his tank and was cool enough to give me his true perc. I dont understand why the clown is hosting in my torch and not my rbta. I have 2 really big roses, about 7-8" but he decides to chill near my torch haha. In my friends tank he had a rbta and the perc was hosting in there, so im confused. Any input or suggestions on how to get the perc to host in the rose would be greatly appreciated. Thanks.
