I have a ten gallon freshwater aquarium that has been fishless cycled. I recently bought five neon tetra, to have three die. I went back to the store and purchased four more neons along with three spotted cories. I am now down to three neons, and one is looking quite messed up (swimming sideways and in circles a lot). My cories are doing fantastic, and loving their new home. The petstores I got them from was petco. I'm sure the reason they've died is because of their poor care in the petshop and because of the fragileness of the fish. I'm not willing to spend more money on fish that will die, and there are no other stores that offer fish in my area. I was wondering if there was another schooling fish you'd recommend (I am planning on getting a dwarf gourami as well) that are easily found in petcos and are hardy. I have been recommended ember tetra and endlers livebearers, but neither are available at the store. Advice appreciated!!!
