Sweet! Ive heard that these need to be Solo unless keeping a school. Hope there is no aggression between the 2.

Congrats on the nice pick up (Tats are hard to come by over here )

I'd say the aggression depends on the individual fish. I have seen pairs of acestrorhynchus falcirostris get along great. My scomb and raph also got along really good. I also think age plays a big role in mixing, and both of mine are still young (7-8").

The one on top is the new tat, and the one on the bottom is my old tat. The new guy was hiding in the opposite corner, and then an hour later I saw my tat huddled in the new tat's corner with him . When I came up to take a picture, they both swam away sort of like a small school of tetras.

Woah, in the pic the one on the top seems to be either Armatus or Yellow Tail Tat. The bottom is 100% Red tail tat. A little skiny. Get them some snacks =].

Looks almost Armatus!!! Except for the tail being way too small.

The new guy does look nice. He is starting to get black banding around the edges of his tail fin.
