Clown knife maybe going to spawn ??

[Wlim]

Hi can any one maybe tell me what a clown knife would look like just before she would spawn I have five two footers in a 1000g pool and the one looks a bit rounder than the rest and is very loving so that you can stroke it and it is not as skittish as it used to be. Pics is a bit imposable due to the fact that they are in the pond. Will try to take a pic or two no promises.

Thanks
