Sooner or later I am going to be rescuing him from the sump as he scoots along the edge of the weir absolutely fearlessly

Tough as nails, I got him from an LFS riddled with whitespot as I couodn't stand to see him there scrathing any more. I was told I would be lucky to keep him 9 months, he is now over 3 years in my tanks.

Used to have 3 I inherited from a mates tank shutdown, but 1 had a parasite in its eye which eventually killed it.

Sally, isn't staying, I was hoping the move to the new tank would resolve some aggression issues between my Nigricans and Desjardini but it hasn't.

Tabby the blue tang is 1 of the most chilled out BTs I have come across, some can be agro, Tab just cruises and chases people as they walk passed the tank.
