You did see that he doesn't ship right...I just noticed that last night in the auction unless yall have worked something out. Post more pics of it if you get it though
I don't know about killing tankmate, but I know they carry a powerful punch even at a small stage. My 9 in flowerhorn experience firsthand after I drop him in the tank with the 3.5 in electric catfish because of his aggressiveness toward his other tankmate. Thinking they would be OK since the catfish is a bottom dweller and the flowerhorn wouldnt try to fight a catfish anyway ..boy was I wrong. After I released the flowerhorn in the tank and walk away for bit, no more than 5 minutes later, I came back to find that the flowerhorn was wobbling in the tank with his head down and tail up half paralyze. I had to again seperate the electric catfish in a breeder for the flowerhorn safety and the flowerhorn didnt fully get conscious until an hour later.
