Its been 3 weeks since my rck has eaten as im trying to get it onto pellets.Its about 30cm.Its starting to sniff at them as im now soaking the pellets in prawn juice to give them a irresistable flavour.it eats prawns no problem but i need to get it eating pellets as when it goes into my display tank with pbass they hit prawn before it even hit the water.Its a very stubburn fish,how long can they go without eating? Its in a tank with a 8'' endli which is eating pellets.any help would be appreciated.
