Do you have dithers in your tank?????? that would give them a constant threat, and they wouldn't be so surprised when you walk in. All my breeding tanks are divide with glass, and sealed, so the dithers are the pair in the next tank. The panduro spend ALOT of time squabbling with the fish next door. You can try a one or 2 pencil fish, but then there is risk of fry straying and getting eaten. Last time i used dithers in the same tank, was with a pair of blue rams over a year ago, and i used 2 young swordtails as dithers. It worked great, the rams had free swimmers, until i gave them a treat of white worms, while the rams where having the WW, the swords helped them selfs to a treat of baby rams :oops:
