Poppie Posted February 29, 2016 Report Share Posted February 29, 2016 HiI have an approx. 30cm black ghost knife that I have had for about 6 months.He lives with a healthy 20cm Oscar, a 20cm Jack Dempsey, 2 bistlenose pleco's and 4 corys currently all in a 280L but I do have a 420L tank in the process of being set up.My question is, my knife fish (who seems very happy all of the time) his white stripe going up along his back is a slight brownish colour and the ring around his tail is very slightly pink - has anyone seen this before? Does it mean is unhappy or unhealthy at all? I know they don't have scales so I really don't want him to get sick. Quote Link to comment Share on other sites More sharing options...
