Nice you got an active mala. Wolf looks good as well ofcourse. As far as the nippyness. I've had plenty of experience with my gold doing so as well. Not sure if you've read any of it I shared as it's scattered. When first introduced it challenged the odoe but got beat up pretty badly. Like three months later after a wc tried the odoe again same thing happened. Never tried the odoe again. When I had the wyckii, the gold bit it after it ran from the black wolf, wyckii quickly bit the gold back, gold left it alone after that. He ate half of a 6" jag when he was 8". They were together for a few months, jag was growing in attitude as well as side. Not sure if the odoe or black beat it up first, but gold took advantage from there and finished it, it to say the jag didn't try to defend itself at first. Jag was a little jerk though, was flaring at everyone. I assumed he caught the black or odoe in the wrong mood, reason I know t was them that did the beginning damage was bite mark size was much bigger than the golds mouth. Few issues I had with the wolf which is why I'm always nervous adding something. The gold tried eating something else I believe but I can't remember right now. Oh it tried fighting the Trachy and sun cat. Lost to the Trachy. The sun cat and the gold went back and forth. Never bothered the bichirs. Can't think of anything else.
