Today i was feeding my fish their faveourite meal a pot containing, Mussle, prawn, squid cockle ETC... and as all of my fish are big i have been trying to hand feed them and i was amazed at how used to me they are. My silver arowana was taking mussles from my hands and some of my larger datinoide. My oscars and snooks were eating loads of prawn. Lungy (my lungfish) was taking food (i don't hand feed due to the risk) and what was the best was that my 16-18" Perruno cat came up and took about 5 or 6 hole mussle by hand and was hungry for more. Experiences like this make the hobby even more enjoyable.
