Great info there Liz, thanks for posting. I have a group of 6 of these in a 125, and they seem to school pretty well. I didn't realize that was normal behavior for them, I was hoping they weren't stressed.
Yours are very nice, awhile back i separated my male from the females.. because i thought the same thing.. but now i am in the process of setting up a tank just for them... three females and the male who are all over 3.5 inches... should be nice seeing them together... having babies.. and male in full bloom...
