Priciest fish I've bought is my lineatus fairy wrasse... I think I paid about $240. Thank god it has made it as long as it has. I may not spend that much ever again on wrasses anymore only because they are relatively short lived (like 7 years) so if you get a really large male it could be half way to its grave.
Sub Category; epic multiple fail expenditures, go! I say, "GO!"
2 Aussie Male Scotts Fairy Wrasses 375$ one did a Free Willy and died on impact! Lmfao and the other never wanted to come out behind the rock work, sad really.
