K so i cam home and saw one hatchet hanging at the top o the tank, when they usually dont, his mouth was pointed up and to the top of the water. None of the other fiah are doing this. Im waiting for the test results. Backround, 40g planted, opperating for several months. I cycled the tank too..should i put him in our empty 10g? Also cycled. He is currently doing backflips and its freaking me out. They dont eat much because they dont hang atthe top much and dont see the food..HELP!!!!
