I've got a two foot, quaretine tank with 1x clown knife, and two stunning red o's at 3inch, i had to temporary but in a 5inch JD. that was very piece full. An hour later i found one of the o's badly battered and most of it's fins missing. I added some melafix and put the JD in a floating plastic bow with holes. Will the o survive? The red colours were amazing. I love all 6 of my o's and don't want to lose any.
