i have 2 ADFs, a male and female which i keep in the same tank. since my female has been introduced to my male, i have realized that he seems to be losing weight. then just yesterday i checked on him and he was beyound underweight! he was also having seizure like jerks and would float on his side or back, and then swim off.. im very worried about him.. he is currently in a separate tank and i am doing my best to get him to eat. i have also seen my female continuously eating. what can i do to balance out the food amounts for the both of them?
