YoYo Loaches- Fighting or Playing

[Ghostknife]

I Have two YoYo loaches, one has been there about 4 weeks, the other about 1 week. The male (Ithink) is chasing the female (I think) non stop. The female has been going white on a regular basis.

Does this mean she is 'in heat' or does this mean she is unhappy.

I am a little concerned for her

Any advise is much appreciated.

P.S reason for thinking male and female. The female looks like 'O Y O' on her skin, the male looks more like 'O V O'.

Thanks again

Hmmm???????

Usually yoyo's are nonstop action, I'm not sure what the going white indicates, maybe it is stressed. I have never had a yoyo go white. Even the experts say it is nearly impossible to sex yoyo loaches with any accuracy.

I have 3, and they usually chase each other around the tank pretty much all day long. I would highly suggest you get at least one more, they need to be at least 3 together, but preferably 5 or more. And then the chasing will be spread out more, so it's not one fish that constantly gets bullied. I had mine go pale from stress, it's a pretty sure sign that something isn't right.
