Hi all, I really want to get a CK but they are rare and extremely expensive (usually $400 - $500). I've found one for $150 but is missing an eye (apparently bitten off by an African Cichlid), but it has awesome patterning and seemshalthy. Should I buy it? Its 20cm long. Would it be alright with a 7cm Giant Gourami and a 14cm Senegal Bichir?
