please can you provide tank size , water results ie actual amounts for ammonia etc ,
the guppies have most probably just given birth with the tetras in the tank aswell the babies will get eaten by them and the guppies themselves

what stock have you got in the tank

when you do your next lot of tank maintenance this week - during your gravel vac check under and in plants for fry - guppy fry will even hide in amoung gravel , behind or beside filters , in plants , the top or gaps in plant pots
