Thinking about stock for my 29g currently cycling (with two 30g HOB filters and heater). I am thinking kuhli loaches, pygmy cories, amano shrimp, and electric blue rams. I would welcome any suggestions on group numbers or heads up on behaviors, since I have never had any of these kinds of fish before (I have had amanos). I'm really only familiar with labyrinth fish and tetras in regards to tank setup and care. I don't think I can get a guaranteed sex ratio on the EBRs so I don't know if having more than one is a good idea, although I would like to. I know kuhlis and cories school. I have glass pebble substrate (4mm pebbles, it's more like sand or really small gravel) and a couple large pieces of driftwood. What else should I add to the tank?
