When my male is trying to mate with the female...I notice his tailed wiggling around. I will then see something(im assuming his "piece") pop out for a quick second and then it shoots back in. My question is, after I see it pop in and out, a large amount if liquid pours out. Is that the sperm? Im sorry about being vulgar. Im curious because Id like to know if they are succesfully breeding and what i need to do. Thanks in advance
