Quick update...
I moved the Phoenix barbs and the rest of the Tinfoils today. Like all barbs it took them about 5 minutes to settle in and start eating like pigs. The owner of a nearby lfs had a tank full of giant danios that he's had forever, he ordered them for someone who never came to get them. So he sold them to me for next to nothing to get rid of them. They look pretty cool in the pond. Probably not permanent residents but they're lighting fast so maybe???? Time will tell.
The rtc/tsn is doing great and eating well. He does this thing with the koi where they just swim around in circles like a chase but I can't tell who's chasing who. Doesn't seem to be any aggression and he can't eat them so I don't know what that's about.
Gar seem fine but they are still very shy and always move to the opposite side of the pond when they see me. Haven't seen them eat any prepared foods yet but I spotted them stalking the rosy reds I have in the pond.
Slightly worried about the arowana. He seems very nervous about all the other fish and hasn't eaten yet. As jittery as he is right now, I'm afraid at night he'll get spooked by the koi/catfish and jump out of the pond so I have 3 spolights over the pond on a dusk/dawn photo timer to keep the pond fairly well lit at night. Seems to help, he's still in the pond. He always got freaked out and would go on a 1-2 day hunger strike when I did any tank maintenance so I'm not overly concerned yet. Hopefully he just needs a little more time.
