I think they probably just need time to settle in but I'd like some opinions to be sure there's nothing else I can do.
We got 2 Angelfish from the local shelter on Saturday (5/21). They are about 5-6" from the tip of their top fin to the tip of their bottom fin. I've put them in a 55g tank which has one tiny Pleco. I started the tank with an established canister filter and confirmed that there was no ammonia to begin with and that there was some Nitrate.
They seem to be adverse to any light - even ambient light in the room, I have the aquarium lights completely off. They basically hover in the corner and then move around (in the corner) a little bit. They sometimes rest sort of crooked. They readily ate some flake food earlier today so at least they have an appetite.
I would have done things differently but this wasn't a planned event - we saw them at the shelter and decided to adopt them. Using an established canister filter from another tank, I thought, would be a good idea because it would hopefully handle the Ammonia conversion, etc. So I was a little surprised to see Ammonia show up on the test.
Do they just need more time? Any suggestions? Should I be worried?
