here is my female prego swordtail that has the gravid spot. the other prego f doesnt have one yet. ive got 4 swordtails, this is just 1 (prego with gravid, prego no gravid, no prego, male)
this is my prego female with a gravid spot. srry you cant really see it, because she was in the plant. this is perfectly normal for a heavily prego swordtail.
same female, dif angle. you might be able to see her gravid spot. its a black area.
just a pic of my male. hes super lazy since the f got the gravid spot. is this normal?
for me, the nonprego f is one of the laziest swordtails i have. this is normal since the 2 other f's are hiding, so the male has given up on trying to spawn wtih them, so he harrasses the nonprego one, and it exhausts her. this is normal, and might happen to you.
srry if im hijacking your thread in any way. aslo srry that i couldnt get any good pics for ya, cuz she was hiding. if you need more pics or maybe a vid to see how they act, jsut ask.
