1. Just something I've been curious about. I took a video of one of my fish doing something interesting:
YouTube - Fish Behavior
A lot of times I see saltwater fish repeatedly swimming up and down the same area or similar behavior. Is this territorial? Is it even known why saltwater have a tendency to do this kind of thing?
2. What does everybody use to take pictures of their aquarium? I have sort of a cheap-o camera and I can't take very good pictures of my fish, what are some recommendations for taking higher quality pictures of fish?
3. About five days ago I introduced two new fish to my 150G saltwater tank. Before, it had a maroon clownfish, a diamond watchman goby, and 11 damsels of different types. I added another damsel and a bi-color pseudochromis. Now of course they got picked on but after a day or so the new damsel was doing just fine and making friends. However, one of the previous damsels, not even the most dominant or aggressive, would just not leave the pseudochromis alone. To this day, he is really persistant at attacking the new pseudochromis whenever he sees it, and for at least 3-4 days now the pseudochromis hides behind the overflow cup and will hardly come out. I've been feeding him there and he eats just fine, he's just afraid of everyone else in the tank. What can I do to help him adjust to the rest of the fish? The LFS
told me he was compatible, but did they lie? I'm hoping to add some more live rock soon so maybe more hiding places will help?
Thanks in advance for your advice,
