Black Ghost Knife potential tankmates?

  • We are currently upgrading MFK. thanks! -neo
Ive got a BGK about 30 cm long, and its the most peaceful fish ive ever had. just keep it with similiar size cihlids, GTs are a good option, eels also.

how about if i start 2 3" BGKs? I'm currently thrifting for a 120G.
That will be fine as long as your tank is planted or that your tank has at least many caves and crevices for them to hide. But if they get big (at least 15 and up) you better transfer one of your bgk one of them will die.
 
I keep my BGK with Cichlids and Dats, no problem. Loaches would round out that tank nicely. :)

at the lab I work in, we have NONE of the black ghosts together. once they get over 2 inches they go by themselves.

I have seen 2 2-inch bgk fightin for hours. i presumed they fought to the death... when i came back there were only one of them.

it might work in a huge tank but i wouldnt do it myself. i have never seen any pics were two adult sized bgk were in the same tank together

i accidentally got a BGK a few months ago.. We named him Babe. He's about 8" long, in the 60 gal tank with 4 cichla orinocensis (all about 4 - 5 inches), 2 electric blue crayfish (adult), 1 common pleco (6"), and stupid shark.

they've been getting along fine since June? We keep a pretty close eye on the fish, if there is a problem we've got other places to move the trouble makers.
 
don't get the green terror or should i say the "MALE" Green Terror. i dont suggest any aggressive type of cichlids esp red devils, jack dempseys, texas, male green terrors, flowerhorn etc. they tend to start off being very aggressive even as youngsters. it also depends on your fish size, tank size, tank set up, and so on.

Beware the crayfish. I had (yes HAD) an electric blue until it tried to grab my 10 inch oscar. Then the O's got mad and tore it apart. But that goes to show, them crays have NO FEAR! Beware the cray that lurks at night and tears apart your precious fish.
