At what point do you separate?

Few pics of yesterday's "frolicking"

I've never kept more than one army in a tank and I certainly don't have the space that you do but that one gash would be enough for me to separate them.I don't like for my fish to fight so I'm pretty much zero tolerant of squabbles lol.
 
Next question do you remove the aggressor or the wounded?

The biggest one is probably close to a foot, there's smaller fish in the big tank, but with these guys tending to hang on the bottom I still can't help but think they'd be ray food (rays up to 16" across).

Could move the wounded in with the baby Aimara but that's probably a gamble too......
 
I would remove the more aggressive of the two but then that may not matter as the remaining army still may turn its attention to the other fish.
 
I've seen wolf's in the plastic reptile cage before. Why not do that for a few weeks till the Armatus heals then try round 2?

I'm going to do this for my Eel when I pick up an Armatus this weekend (obviously opposite species but it's idea).
 
Tough question ... i'd def say take the aggressor out, not the wounded ... the wound should heal fine, although that is a nice one, you sure thats from another Armatus? I agree with Krich, as far as zero tolerance of aggression, but i usually try and ride it out a little, not remove right away, and hope they settle down ... i know its a gamble, but you know your fish better than anyone ... a wound is not as bad as the constant bickering and harrassing that eventually stresses the fish out to the point of no return ... if he's not constantly getting beat on, i'd say go for the gamble ... tough gambling though, with such lethal teeth where most victims dont usually survive too many hits .... so i guess in the end, i dont know man, no easy solution

Wow that's a gash that guy will remember. I like to move the aggressor vs the injured purely because I worry about injuring the already injured fish further by netting. Also the aggressor probably will do better with the aimara, never kept aimara but even moving and injured fish in with my red wolf has ended badly. It may notice its in stress and injured and trigger an attack

Little more info......

These guys (3 Armatus) are in a standard 6x1.5' footprint 125 gallon. Have been fine till a few weeks ago, all 3 have been back on feeding binges and it seems like they've just decided the tank isn't big enough for all 3. The bickering seems pretty steady. As long as all 3 keep to their areas it's fine, but the ray in with them (10" male)has figured out the art of eating floating sticks off the surface so whenever there's movement outside the tank he assumes its feeding time and begins pacing the tank in mid water and as soon as one of the Armatus dart out of the way they are attacked by the Armatus whose territory they just darted through......

I know gashes are to be expected, but this looked to me like a pretty serious attempt. I guess it "could" be from the Iguaza Wolf but as narrow as the bite is I highly doubt it. Plus out of focus pics seem to show 2 pretty big puncture holes like the fangs Armatus have. It looks worse in person.... Just a gaping flesh hole. My concern is it looked like an actual bite and shake instead of just a simple shanking. More of an attempt to kill rather then warning.

I'm super excited to have this problem honestly...... Only another 4-5" and I'll surpass all other attempts to raise Armatus I've had in the past. Hoping that having pellets be a big part of their diet will eventually lead to an adult fish and hopefully close the chapter on my inability to raise these things...... (knock on wood)

Maybe it's time to give that angry guy a shot in the big tank, I'm just scared that one disrespectful jaw flap might get him shredded...... :(
 
Add more rays so they worry more about the them and have less time to worry about eachother.:)
