i wanna know how this is going honestly. i would love to have 2 rhom's i a tank to live in harmony. i would just put 2 huge caves on each side of the tank after seeing that one picture. maybe plant the middle of the tank nicely. i've been lookin @ the amazon biotope or watever. thats really what i want to try. if each had plently of space and fed on sep sides of the tank. would be the ****. and whoever has that profile pic of the white looking pirahna. thats bad ass. have a black with red eyes, a white with red eyes. "ebony, ivory. live in perfect harmony" lol
