Hello first time here , have recently brought a red tail catfish that is curently around 8 inches long and 4 months old I have had him 4 days and in that time I cannot get him to eat , I currently have him in a 200 litre tank but have plans to get a larger tank when required my water tests have shown nitrate to be 90ppm nitrite is at zero ph 7.2 and ammonia 0.25 , is this normal for them not to eat ? Any suggestions would be greatly appreciated
thanks in advance
