Tigrinus aggression?

[rodger]

I am growing out a Tig and a Leichardti in a 40B. Both are about 8 inches now. Bare bottomed and some floating plastic plant. No lighting. No caves for the Tig, he stays between a large sponge filter and the end of the tank mostly. They will be split into private quarters in a couple of months as another tank is available. I understand cats will eat what fits in their mouths, but he killed a Slobbering Cat by chomping the caudle peduncle. It died from infection. Today, I see it has bit a chunk out of the aro's tail fin. I see tons of pictures on here of Tig's in a community tank with fish smaller then they are. Is mine normal, or just a little bit more aggressive then most?

If he is well fed, then this is not a predatory attack but perhaps a territorial one. I'd try a bigger tank and see what happens. Lei aro is debatably the most aggressive aro. It might have provoked the tig too and that was a defense/retaliation/pecking order kind of thing.

This does seem territorial. Tail biting seems very universal for catfish fighting.

Hopefully I can get them split up before I have a real problem. I'll try and keep the Tig fat in the mean time.

maybe try a PVC tube... give him something to guard that's big enough for him to "hide in" so then the arrow has a place he knows to avoid.

Will he hide? My tigs and jurs never hid. Doesn't mean none do.
