The inch per gallon rule has to go out the window with Jags. I have two small jags in a ten gallon. They are pictured below. The lighter colored one chases the darker striped one constantly. Now the darker stripped is burying himself in the gravel looking for relief. I have plenty of hiding spots but it doesnt matter. The aggressive jag is on a seek and destroy mission.
