double checking my males,& the first male probed fine & then probed my smaller albino male 500g & the ball tip started to pull out the Hemis! wow scared me real good but was very carefull not to pull them out or damage them,they went back in place & looked ok never had that happen,popping still freaks me out but Im getting better at it poped my larger male & found sperm plugs my wife did'nt like that yukky LOL!
