Well, I've got the double hex set up - gravel, silk plants a couple of hidey holes and that's it. The tank has UGF and one heater. The lights over it are coloured so that rules out live plants and now I want to get a betta. Do I have to cycle the tank first :what: I thought that because it was so small (about 4.5 gallons each side) that it would be ok to add just the one betta for now, and then a few weeks later when the tank is more stable, to add the clean up crew. I've cycled 2 tanks already, but they were much larger. When I do add more fish, what can I put in with a betta in such a small tank? I want a 2 or 3 corys for cleaning and I thought maybe a couple of something else, but what something I don't really know Any suggestions please
