First of all hi to all I am a newbie to this site I have been fish keeper for only 2-3 years now and six months ago I saw two beautiful baby Oscars and couldn't resist they first went to my 50g tank for 2-3 weeks then moved to my 75g they are now 5 & 6 inch long and sexy as they come but I Han heard that Oscars love earth worms can I get these from a tackle shop / bait shop is there anywhere else not want to dig them up worried about parasites is there any other bugs/insect's that they can eat. Thanks and sorry about the long question.
