So I was re-adjusting the intake part of my filter system, and I hear a big splash! I thought it was just another one of my arowana's spazzes and I looked around and I saw it flapping all over the ground! As soon as i grab it and throw it back in the tank, i hear another splash..... great! 2 arowanas jumping out of their tanks in one go! One has 2 injured scales from hitting my piano edge but they'll live... ruined my night though!
