hey mmystix212,i saw the dovii dissapear at times and i saw no iredesent sharks but maybe thats cause i stood in front if the amazon tank to long.i wish they had more freshwater stuff too.years ago,bout10,i went and they had huge bass,yellowbellys and silverperch but i didnt see em this time.the african four wheel drive is cool hey.i guess lil fish survive as the big ones get fed heaps.did u mean the lil ones in the amazon tank or in the saltwater tanks.finally how awesome r those big barra and mangrove jack.
