I have seen it in the garden shops around Sac but I always go back to the pet stores to buy it. It is more expensive, but at least I know what is in it. I never know for sure what is added to the peat at the garden shops. At the pet stores you know it is meant for your tanks. The one thing to ask you is, like someone else has mentioned, did any other tank mates die as well. If so, I would consider the peat as being the carrier of some contaminent that has cause your Ramirezi to die. My suggestion before putting anymore fish in that tank, is to take all the fish out, bag them or whatever, and then strip down your tank. A good thing to use on cleaning it is vinegar. Rinse the tank and then set it back up. Place your fish back in it. Don't use the peat you had added to the tank previously. Check your fish for a few hours to see how they act. This way you will know it isn't your tank. Also soak all the tank gravel, decorations, filters, etc. in the vinegar. The best way to find out what happened is using the process of elimination. Kaycy
