Hello, first off i have a 55 gal tank with 5 oscars and a pleco. 2 Black Tigers 6 inch, 3 Albino Oscars 4 inch. 4 of my Oscars eat feeder fish with no problems. one of the black tiger oscars shys away from the feeders and the colours change from her natural look to almost like a lighter tan striped with the black and faded orange. Is it just a shy fish or is she intimidated by the feeders in her tank, even tho there are other Oscars. Is there anything i can do to encourage her to eat the feeders?? It has no issues eating pellets or the frozen bloodworms, brine shrimp, daphnia, glassworms, any of this stuff, i know it will not starve, i just wanna know why she changes colour and wont eat them. Thanks in advance for any help you can give.
