I dont think i said but if they dont take pellet then its a pain at times but stuff prawn or what ever with the pellet to get them fat, then when a bit bigger you can fatten them up and then starve for a few days or a week and feed them pellets, i added quite a few and just waited for 10 mins then removed whats left, it didnt come first time but they mouthed the pellets over a few days then started to take them and love them now.
