Hi all, this is my first post, but took a long time reading the forum. First of all, sorry about my english, I'm from Spain and my English is not too good. the fact is that I am passionate about sharks, dream for many years to have an aquarium with sharks and I think now I have the means and the space to do it. I am building a 500 gallon tank (aprox), and I will make a Mediterranean ecosystem, for ease and proximity to the sea and also because I am passionate about this ecosystem. My question is limited exclusively to personal experiences with the type of shark that I will keep, the greater spotted dogfish (scylliorhinus stellaris), is very difficult to find information on this species with regard to their maintenance in captivity, it is not a shark common in home aquarium, my question is directed to their behavior in captivity: feeding, hardness, compatible species, agression... any personal experience would be helpful. Thanks in advance to all, and great forum by the way! Cheers
