It is no trouble at all. It is why we are here! The first thing to check would be water chemistry. This can be done using a home test kit or by submitting a water sample for testing. Most pet stores will do this for free or for a small fee. Aim for 0 ppm ammonia and nitrites with a nitrate level of 20 ppm or less. Perform a partial water change, no more than 30% total volume, daily to stabilize or improve water chemistry. Use only aged or conditioned water that is temperature matched to prevent stress or shock. The species of fish you have do best in the mid to high 70s F up to about 82 F. If you have a newly set up tank, it may not have cycled properly or adequately. This would have led to toxic levels of ammonia which likely killed your fish. A tank needs to run, without fish ideally, for 4-6 weeks to establish a Nitrogen Cycle. This time period allows beneficial populations of bacteria to colonize the substrate and filter media. These bacteria are responsible for breaking down ammonia and nitrites into nitrates which can dissipate naturally, be used by live plants or be filtered out. A tank can be cycled with fish, however, close monitoring of chemistry and frequent water changes are required to minimize the risk of fish loss.
