I will gladly be second on the waiting list!

From the sources we placed on here, spawning times and temps are:

Spawning occurs from late Mar into July (72.5 to 85.1 deg).

and

Based on laboratory studies, March to May (later stage larvae prefer temperatures of 28-34 degrees C; Negus et al. 1987).

So your brood stock should have just started spawning and may not be more than a 1/3 of the way done...

I hope your chubsuckers make lots of healthy babies!
