Taping plants upside down on the lid to prevent aggression

[daveman12345]

I put alot of floating vines, lili pads and other plant to decrease the aggression in my community silver arowanas. The agression seemed to improve a bit as time went on and removed the plants and there was even less fighting. I added some plants back and they started fighting again. As of now it seems to be worse with floating plants.

My tank got better without any aggression problems. I ended up taking out the plants because the moisture got to the tape and it looked slimy. Though, just leaving floating plants and other obstacles so that when one fish goes one way, another can't jump at it, definitely helps.
