will 2 females lay eggs together?

[sasikan]

hi do you think 2 females Laetacara araguaie would lay eggs together (this sometimes happens with my Discus) i had 4 together in a aquarium 2 of them have eggs and ( babys now) so i gave the remaining 2 a aquarium of their own, and now they have laid eggs at least 4 times in 2 weeks, the eggs always turn white . do you think this would be 2 females i cant tell them apart but also i cant tell apart who is the male or the female in my first pair of Laetacara thanks
