LFS in Ontario had them but so far people who did buy them are reporting huge losses already.
I feel these are much more fragile than Cardinals/White Starry Nights/Ensifera etc.
From what I read about them they live off a particular sponge that grows in the lakes in Sulawesi and also the biofilm on rocks there. They need specific water parameters and temps to keep them happy/alive.
Even a drop in the temp from the LFS to your tank would be a problem.
Too bad, because they are especially beautifully marked.
