new guppy fry magically deposited inside tank nursery - totally serious

[LuluH]

Last night I let out my two guppy fry now 3 weeks old into the main tank, the nursery stayed floating in the tank, it has many slanted vents along either side for water flow,, cleary now empty. I woke this morning to a nursery with approx 10 tiny new fry inside,,, an absolute mystery,, has anyone ever known guppies to enter a segregated nursery, deposit live young and leave ? i can see the older two in the main tank, approx 3mm long. I will try to take photo of the new fry, translucent and safe in their little nursery attached to the side of tank

maybe the female gave birth in the tank and the babies went into the breeding trap for protection or where drawn to it by the light

we are now thinking the nursery was at an angle, full of water, half attached to tank side all wonky after letting the two large fry out., the fish are inquisitve about the plastic cube so enteted it... and when a female must have popped into it,,,,and gave birth, then swam out,, but we didnt see this, we saw the wonky nursery and readjusted it back to the water level, trapping the tiny weeny mew fry.... what a magic mystery
