Hello, this is my first post to this site, and I had a question about my guppies. I bought 7 male guppies from PetSmart yesterday, with my 10g tank fully prepared two days beforehand. I brought them home, acclimated them (probably somewhat roughly or not too well because I'm an idiot), and plopped them in (I did remember to not put the "bag" water in my tank). I went to bed, woke up and 3 guppies were dead. I went out later, and one more died while I was gone. I am looking for possible solutions to make sure this doesn't happen next time, and I'm sure most responses will be "cycle your tank". However, I have never had any issues with cycling, and some fish (forgot exactly what they are) have survived for over a year in a tank that was set up while they were in the bag, at my house. I washed everything beforehand, including gravel, I have a thermometer and heater, set to 78-79 degrees, and I conditioned my tank. My main question is, will I have to continue netting dead fish bodies out of the water, or is death done rampaging through my tank? Also, besides getting my water tested and cycling, is there anything else I can do to make sure that my new fish (that I shall purchase in about a month, after allowing my tank to cycle) have a smooth transition from shop to tank?
