i know commons are nothing special but i have whitnessed this male accumulate two different collections of eggs at once,, wanted to show it off, and ask if anyone else had seen this before as it is a first for me ..
I have a male and two female marbled BNs and often both the females lay in the same day. I suspect the pherimones from one laying exites the other female and she lays too.
i once had a brown who hatched 2 seperate batchs of eggs in near by caves he produced 150 plus young he is now hitting 175 young every 4 weeks just had 175 1 week ago and he is back on eggs now.these fish are amazing.
