Your tank hasn’t cycled and your parameters are probably way off. Don’t add anymore fish! Take a sample of the water to your local pet store and have them test the waters parameters! (Ask for actual numbers! Don’t accept they’re fine as an answer) Then come back and post them here so we can help you address the problem correctly!Adam85 said:Well we let the tank run for two days after putting tetra safe start in it before we put the fish in. We put in 3 bala sharks, 4 neons, and 2 glow fish. They lasted about an hour then all died. We then were told by the place we bought the fish to put in stress coat. We did and got more of the same fish with the same results again. What am I missing?
