I'm now broke after spending close to $150 on 5 roseline sharks, would have bought more but the LFS ran out. Hurts the wallet but they are worth it, they're beautiful and appear to be pretty hardy so far. If anyone was on the fence about getting them, I say go for it. They show no sign of aggression towards my smaller fishes and they ate right away. They're active swimmers that aren't shy and make a great schooling fish for the larger tanks. The LFS did confirm for me that they had seen one that was over 5 inchs long. Oh, if you're reading this Mooman, know that your constant hyping has finally made me get a pair of apisto cacatuoides. That and the LFS finally had some in stock.
