I have a captive bred Bangaii and for the last 3 days it has only what I can call a seizure when it eats. As soon as I feed the brine shrimp, which I've fed it since it was small, it eats at a furious pace, starts twitching, zips around the tank, then stops and sinks to the bottom sitting upside down looking almost dead. It slowly breathes then after 5 min or so rights itself and with 10 min it's fine. Anyone else experience this? Any ideas on how to prevent it?
