I'm about ready to put water in my tank. I want to have some kuhli loaches and zebra loaches but here they are VERY sensitive to water quality. I'm wondering should I do a fishless cycle or through some fish in and use stability? I do want a variety of tetras too. I'm not buying my fish locally, I'm going to order from The Wet Spot. It's actually cheaper to do that then buy cardinal tetras at Petsmart for 4.00 each. Any suggestions are welcome!
