So I was doing great as a fish mom with my 1 gallon betta tank with 1 betta and 2 neon tetras. I quickly realized it was time to get an upgrade for my poor betta and got a ten gallon aqueon with a filter system and a heater. I used white gravel, plastic plants, and silk plants, and a fake wood decor piece. I use aquasafe, easy balance, and cleaning bacteria to start the tank and soon put all three of my fish in. Everything was great and thriving well! Then, one day i found one of my tetras dead and i scooped him out and did a water change. I got more tetras and acclimated them before adding them to the tank. I always use easy balance and aquasafe when adding new water. Itís possible i put in more than recommended but i have heard that theres no such thing as too much. Everything seemed to be good again until i came home to the four new tetras dead after only 4 days in the tank. The original tetra and betta still fine. So again, water change and added water fixers, but this time i bought test kits (not strips) and more tetras. I discovered a slight bit of ammonia and added amolock as well as did a water change. I thought everything was good again until i discovered my betta dead... i dont know what else i could be doing wrong and my goal was to save these fish from pet stores so please help!!! Iím scared to get more fish
Also took my one shrimp and last Tetra completely out the tank and in a separate bowl with all new water and they are both dead after 24 hours. I dont know what else to do please help!
