These are 2 of the 3 Cichla orinocensis that I received from Mark. (Discus Origins) at Ocala Aquarium.
I recommend this member. He was recommended to me...
I've never had any fish of any size that can eat more, per weight than these three fish!
I fed them little guppies while I was looking for Mysis and Bloodworms. No matter how many I tossed in, they were eaten right away.
Crazy!
I'm having 6 orinos, little bit bigger than yours. This is the first time I'm having Orinos and they definitely have a lesser appetite than the other cichlas I've had (eg. tems, monos, kels & azuls). But I'm feeding frozen not live.
I've set up a separate grow out/quarantine tank for guppies so that I have some on hand to supplement the frozen Mysis and Bloodworms while also trying to get them to eat some tiny Hikari.
