I noticed that about a week before my albino ice blue started carrying eggs in her mouth. that the male went from 2 egg spots to 4. then also the female got 2 egg spots on her. right after she started carrying the eggs. i was wondering if anyone else has ever noticed this before. like thats a sign to tell they have become mature. sadly i dont have enough tanks n fish to test this out so i was wondering if anyone else has seen this. just a theory...
