They might be able to, however that is risky considering the rarity/cost associated with them. I looked for these fish for a full year. Nobody had them. Was starting to think they wouldn't appear in the hobby again. Then Rapps got them in. I am trying to rehouse a 8inch Red Devil. If I can find a real home, not a LFS that is going to put him in a 20 gallon, I am going back to Rapps for as many of the Cobras as I can get.
