is a black ghost knifefish gonna go with 2 columbian sharks and a tire track eel???

Question

the tank is 75 gallons and the columbian sharks are 3 inches and so is the eel

Answer 1

Sorry, but no. Black Ghost Knives are peaceful fish, and are too fragile to be kept with aggressive species, especially fin nippers. They also emit a mild electrical charge that can be annoying or stressful to other fish in the aquarium, especially scaleless fish (like your sharks and eel). Also, Columbian Sharks are brackish fish, and although they can tolerate freshwater when very young, if you keep them in freshwater (which is what the eel needs to survive), they will develop deadly skin infections.
That mix of fish would be overstocking your 75 gallon aquarium, and with fish that all prefer to swim on the bottom and hide. Your ghost will hide and live on the bottom, so it cannot live with the eel, as the eel is aggressive and has the same preference for hiding, and it cannot live with the columbians, because they are brackish. The columbians and the eel also cannot live together because one is brackish and one is freshwater. I would pick your favorite of the three species, and then find other fish that are compatible.

Answer 2

yes well make sure their all about the same size now. Also get a good hiding spot for the knifefish like an ornament where it can go in and hide. They love it and keeps them less stressed.
