The big guy is pushing 80cm and had broke a few lids on the 8foot tank so i moved him out to the 9000L pond 2months ago and he has not eaten since, the water is perfect, nitrates 5ish ppm, ph nuteral, temp 27. but he just wont eat, the only luck i have is about 6 hakari sticks once a week. he is verry skinney now but still looks heathy and is acting normal towards other fish. he used to devour anything that would fit in his mouth, prawns, pellets, chicken and up to 4 blue pillies some days. ive tried soaking the food in garlic but still nothing, any ideas? ide love to here them...
