I don't want to sound like I am lecturing but we do keep these animals in our homes as pets but we should also ensure that we are providing everything they need for long term success and healthy living. From what I have read over the years, keeping a shark or multiple sharks, is not an easy task in the fact that we must provide them with ample space to swim/grow/live and also make sure that their tank mates are also not going to bother them. Many would say that tangs and puffers and triggers do not make good tank mates for sharks as they are pickers and will most likely pick the sharks. Also corners of the tank can and most likely will negatively effect the sharks snout as they swim into it. I have read that this can cause deaths as well. Please take this into consideration and do research before purchasing these animals. I understand that you may be able to provide them with care for their lifetime as you may have a larger tank to transfer them to but as many would agree with me on is that we are in this hobby to care for these creatures for their entire life. I hope this helps.
