The Puffer Forum

Oh sorry. It's Tetraodon nigroviridis. My tank is quite little about 7 gallons. There lives two tetreodons and to Chromobotia macracanthus. I don't know the wather parameters, i change half of wather after 3weeks. I use just some neutralizer that clears the wather. The aquarium is about 8 months old...
