hmm, you may not have to...I just put some of the water from my current tank to a 75 gallon and put my blood parrots, gar and bichir to the 75 gallon until they grow bigger and able to compete for food with my Aro, TSN and Clown Knifes.
So I may be able to get the Juruense anyway and put them in my 75 gall grow out tank and when he get larger to about 12-14" I'll put him in the 240
