What is growth rate of these goonches??? i know the yarrelli grow huge but how long does it take to grow 2 feet?? i currently have a 75 gallon tank with 5 inch bichirs. How long can I house one in?? what is the ideal temp to keep both species together?? will they cohab?? i read from a gooch thread that the goonch dies easily. what do i need to do to raise them healthy?? I hear that strong current and cool water is ideal. is that true?? Where can a get a bagarius bagarius or yarrelli at 5 iches?? Are they super aggresive because I want tankmates.
