Question: Axolotl assault.....should I separate them?

Hi everyone, I'm somewhat new to axolotls, I have two GFP axies; one melanoid, one albino, both are about 5 months old now. The melanoid was a couple weeks older when I got them and has always stayed about an inch or two larger than the albino...the melanoid one is also much more aggressive especially at feeding time. Both are now between 6-8 inches long now. I noticed last night at feeding time my poor albino is missing his "hand" from his front limb, and one of his gills was bitten almost completely off....it seems he is being bullied by the melanoid axie. They are in a 29 gallon tank, heavily planted with several hides; and I feed them Rangen salmon pellets three times a week. Is it "normal" to have occasional tank mate injuries like this? I know axolotls have amazing regenerative abilities; but am still concerned and not sure if I should separate them (I would prefer to keep them together). Does increased feeding reduce aggression? What do some of you axolotl experts do if a tank mate bites off a limb/gill?

It's completely normal. Axolotls are opportunistic feeders, and will snap at anything that moves. Increased feeding may decrease their snapping at each other. You can also try to feed them at opposite ends of the tank.

If you notice the bigger axolotl is causing a lot of injuries on the smaller one, you may have to invest in a divider to keep them separated. As far as what happens with injuries, I'm of the 'wait and watch' campaign. I don't do anything with an injury unless it starts looking fungus-y or infected.
