Dude, you literally didn't even let sit for more than 6 hours. Not everyone checks the forums constantly through out the day. In regards to your question, I can say definitively either way. My best guess would be that having a fish be dominate wouldn't have a long term effect on development, but you would see more color while they were dominate. As far as hiding, you should have somewhere for the fish to go to feel comfortable, other wise they will most likely be more stressed.
