I had suspected she was pregnant but ive had her for over a month and no fry yet. Well today she looks huge and now has mucus like trail? Ive read conflicting info that its usually parasites. But im also reading that live bearers release this before they give birth. If anyone can confirm that its part of labor i would feel better. No other fish in tank appear effected. If she is starting labor i need to get her in the fry box!
