There is something wrong with my Spotted Gar. I left for Daytona Saturday morning, I dropeed in about 20 comets and about 20 Rosy Reds along with food for my other fish. I came back last night turned the light on and everytrhing was fine as I began to walk toward the tank my Spotted made a full dash straight up out of waqter and slammned into the hood thrashed around alittle and then began to sink while he was sinking he began to pulsate and a stream of air bubbles came from his left gil. Then he fell to the bottom and layed there upside down, I flipped him over on his belly and he sat there for a couple minutes and bagen swimming again. Then this morning I fed my fish and turned my filter on half power when I went to turn it back to full power he started thrashoing and rolled over again and began pulsating except for when I went to flip him over he kept rolling back onto his? Please help me fix my Spot!
