OFL replied the topic: Re: How do I feed my O's bloodworms? I would take them out of the freezer a couple of hours before you intend On giving them to your fish. When you drop them in they will stay bunched together for a little bit, this is normally when the Oscar jumps on them and swallows the blood worm hole. However, my Oscars will quite happily eats one blood worm at a time.
Some of the best choices for oscar tankmates are some of the larger catfish, silver dollar fish and many of the semi-aggresive cichlids, like convict or earth eater cichlids. But while some fish may peacefully coexist with one oscar, another oscar may relentlessly attack the fish and even kill it.
