I got a 15-18 inch marbled Motoro Female. She is alone right now and has a bad attitude. she tackles the glass whenever i come by and tear'd up her tankmates (not stingrays). she is also an extremely picky eater. she started to stop accepting swai and squid. eats tilapia but very slowly. She does however like smelt/anchovies. I will be leaving This coming sunday for a week so i want to make sure she is well fed before i leave. But currently i am only feeding about 1-2 large smelts a day. the smelts are gutted so i put about 3-4 massivore pellets in the organ cavity (she isnt pellet trained, but i can still trick her lol). Each massivore pellet claims that they have the calories of 1.8 goldfishs. assuming i only feed once a day with a smelt with only 3 massivore pellets. thats about 5.4 goldfishes. Is this enough? i am prepping her for breeding but my i have no males right now. but currently my main concern is her weight. ever since she stop accepting other foods she isnt as plump anymore. she isnt skinny but you can still notice her 2 back bones points. any recommendations?
