Well sh#%, you sure they sold it as a haddon?
Dots are there, means it is a gig?
% of it making it?
A lot more difficult to keep than a haddoni.
You really think they are more difficult to maintain, or just harder to get one initially established due to poor shipping, etc?
Many people that I've seen reports from that have gotten them established (a couple of months, say) under good conditions of lighting and flow seem to think them quite hardy, even surviving such events as total tank failures where they are exposed to air for substantial periods, etc.
