^ Zap mines at 7.5 and ive seen some measured up to 9 inch!! I dont think anything but a fully grown jar or silver could really take it out. A black might be a good idea, theyre mouths are smaller then that of jardini and silver, superficially at least. Mine has gone from 3 inch to 7.5 in less then a year.
Gobys work, my buddy keeps a marbled w/ his red wolf and they leave each other alone. Theyre also really into silvery fish, so if you put a silver aro that was too small the red might be able to eat it or kill it. Be careful about fish that move a lot, ive had to slowly acclimate my own red wolf to moving fish and in the process hes killed and partially eaten 5 giant danio, a 4 inch heckelli threadfin, and a small ropefish (still was longer then the wolf). Dont underestimate these guys. Also make sure you have a tight lid and put things over the heater holes and such.
Bichirs are great IME as tankmates for red wolves, especially if kept with them from a small size. My red piles w/ my bichirs

So be careful, dont be afraid to lose some attempted tank mates, and make sure the lid is on AT ALL TIMES. If i leave mine off when im refilling the water change cooler he jumps. Every time.
Be very careful w/ your fingers, ive heard rumors that full grown red can take fingers off. I doubt anyone on here wants to test that
