Major problem with Piranha Tank

  • We are currently upgrading MFK. thanks! -neo
I agree with trying to egg crate them off in the tank if possible, especially if they start showing signs of agression.
 
If you only have one filter on a tank its not enough, for this very reason.
 
Put filter from 20gal and piranhas back into the 75gal and go buy 2 new filters so you have an extra one next time. The same thing happened to me once and now I always have a new filter and heater on hand.
