i have just got 3 new silver dollars. they are all in tiptop shape, but are hesitant at exploring their new tank. its nice and has a alot of swimming room, and lots of hiding spots, but they just picked out 2 little spots to go to. i think all they need to do is warm up to the tank and tankmates. how long does it take for silver dollars to adjust to a new tank?? they are currently with 8danios, soon to be with 4pictus, cycled tank, diet of flakes ant boiled crushed carrots.
