So I recently stocked my tank. I have 5 Emerald Rasboras now with a Honey Gourami and 4 Oto Affinis. Question is why do they freak and hide when I come up to the tank? They seem to come out and explore the front of the tank once I'm away. I figured they were shy when I researched them, but didn't think they would freak when I came up. Also, is 5 enough or should I up their count by adding maybe 2 more? Are they more of a schooling fish?
