I agree with necro. I think all catfish aficionados dream of making their way into saltwater cats. And of course the Jordani cat is generally the first that comes to mind. Most of these saltwater cats come from the family Plotosidae or eel tail catfish. Aside from the Jordani catfish i have found a member of this family to be the next most common for saltwater cats in my area. Plotosus lineatus is a schooling fish when young so you'll often find them in groups at your LFS though generally as they get older this social behavior fades and your large group will need to be trimmed to reduce fighting. Ive never seen an adult in person, only the juveniles in the 3" range.
