So I've been under the assumption my zz rd was a female due to lack of kok. It is about 4 1/2" long now and I had to put a divider in my 130gal. that houses my brute jag and put the rd in. That was 4 days ago and I have noticed every day this week it's kok is getting larger. I guess it could still be a female but man does it get mad when the jag gets near the divider! tail slapping at the divider and cutting through the water. I have been taking pics every night to compare the growth.
