Hey guys I have a wild kelberi peacock bass that's about 8" now, I bought him about a month ago at 7". Right now I feed him live shiners that are wild caught and quarantined in two different tanks. Live shiners at the moment is his staple because I'm afraid it will be impossible to get him onto pellets. The guy I bought him from was a universally more experienced fish keeper than me and has had years of experience with kelberis and has had this one ever since it was 3". He owns a 400 gallon with 3 breeding BD rays as well. And even he couldn't get him onto pellets. So anyways I want to know if he could get malnutrition off of live food? He hasn't been showing any colours really since I got him but he was eating fine. He also eats whole night-crawlers is that any more healthy or cleaner? The original owner had him on a diet of worms anyways. And also one last question. Would he eat a stingray half his length in disc width if I didn't feed him for a week? Because I go on 1-3 vacations a week long every year during the summer and I don't want him to starve or eat a stingray that I was thinking of getting soon. CAN ANYONE HELP???
