You know I was watching these guys pretty closely yesterday and now I am leaning towards murder again. Believe it or not the Dovii is running the show now, despite it's size. It even gill flares at me and shakes all around like a tough guy now. A bit of an attitude adjustment from last weekend. It's also got the larger Jag hiding in a bush and the smaller Jag hiding behind the filter tube. I'm impressed. I also think that maybe three was company for him and he was quite possibly the murderer. My new theory was that when I shut the light out Wednesday night the Dovii sprung into action. He killed the Jag almost immediately and quickly ate him entirely. Now he had all night to and day to digest his victim and drop anchor before I returned from work. During this crime he also got to show the other fish who was boss by punking the biggest Jag in the place. Now the others got to see what they were in for, possibly explaining all the color change the fish had the next day. It was a change of guard, which I would think came about because the Dovii was added to the tank separately almost a week after the 3 Jags, and was rudely welcomed by the gang. Now he showed the remaining fish what he could do and has earned his respect, and so he claimed the flowerpot for his territory. Now the order is settled I think, at least until two of the three start mating. Also, there is still no smell or sign of a jumper so that helps me support my murder theory in my own head. Sounds good right? I'm feeling better with it. Maybe this is the answer.
