Hi all, I am new to the hobby, and recently started a 10 gallon tank. It took almost exactly 4 weeks to cycle, and our current parameters are ammonia 0, nitrite 0, nitrate 10, pH 7.2. About 6 days ago we added 2 male platys and a dwarf gourami. One of the platys is tormenting the other, constantly chasing him into the corner behind a fake plant. He barely lets the smaller one come out to eat. How concerned should I be? I know that male on male aggression can be an issue, but I was hoping to avoid any fry so went with boys. Should I give it more time or bring the bully back (if they'll take him)? We were hoping to add another platy and a couple shrimp once we're sure the tank is stable. Thanks for any advice. This forum has been super useful as we were getting started!
