I have had these 4 individuals for over a year. I moved them from one 55 gallon tank to another 55 gallon tank 6 months ago, hoping that the different landscape and territories might make these two individuals stop fighting. They have not. I was watching them going at it last night for no less than an hour non-stop. And after consulting with Shari2 about something, I realized I should post my query here.
The pictures below were taken last March. The loaches are bigger now, but still go at it for hours with all color draining from them. Should I just separate them? Or just let them do what they're doing. It looks exhausting, but no one's been injured or gotten sick from it yet. I could add a couple more to this tank if that would help, but I am slightly hesitant since the other two lead peaceful and lazy loach lives, sleeping beneath driftwood all day while the others try to kill each other.
Thanks for your advice.



Take care,
Mary.
