i just got three angelfish the other day and have now clue how to take care of them. the first question i have is, are they an out going fish that likes to swimming around are do they just like to site around and not move. how do i feed them, i bought the frozen brine shrimp and they are eating it after it melts and goes to the bottom of the tank where it is harder to find. they aren't going to the top to eat the flake food. what can i do to get them to eat the flakes on top?
