Jardini question

  • We are currently upgrading MFK. thanks! -neo
jardinies hate each other and any other arowana look-a-like fish.
my brother got bit once, he was going to feed my jardini a worm and it jumped up and out of the water and bit him right on his finger.
my brother was shocked. at first he felt okay and then a minute later he sees that his finger is actually bleeding. there was actually a cut.
 
so what are your methods of cleaning the tank?
