I have a 125 gallon tank with a mostly bottom dwelling stock. The LFS just got a large shipment of red fin tin foils and red hooks which I can't decide which to get a small school of. I know they need to be in groups of about 3-5 and get large fast but I have the room. I also have a Mono Sebae which I don't know if the Hooks would nip or torture. I've kept tin foils in there before but they all died during a water change from a heart attack or something. General advice and experiences are all greatly appreciated. Thank you!
