Ok my GATF is about 5" and I have in a tank with a payara and a bunch of Cherry barbs.... I throw in roseys every now and again...The tank is planted. Lately Ive been seeing fish just chewed on or sides ripped off... Its like hes torturing them... The barbs have gashes out of there sides some alive some died... The roseys that used to swalled whole are missing heads or tails. Hes going F'in Crazy... I duno wats up... the fish are in there for him to wat... but hes not wating just killing...It looks like he hasnt eaten for a few days just keeps killing... Am I doing something wrong???
