i used to have a 125 with 120lbs of fiji pink sand and had 2 dats and 7 fronts in there... now i have a 240gallon tank with 120 lbs of fiji pink sand and a silver arowana and 3 dats and 7 fronts o and a compressorceip/ calvus... not sure which is what... its yellow though... im thinking about throwing in one more golden dat and maybe a jardini... good idea or bad? and adding in 120 more lbs of fiji pink sand...
