I have had my guppies for about 2 months now and she has been pregnant from day one but has never had her fry. Have introduced her to a breeding trap to protect from my pleco and other fish. Have had her in it for 2 days now and have already seen tiny fry. Dont know if they are still there tho, will they just leave when they want? Also how long should I keep her in there for? Cheers
