Okay, so last week I was lucky enough to find some threadfin cardinals (apogon leptacanthus) from an online vendor. I've got five of them, and they were intended to be the only fish in my 40 gallon.
Thing is, bold they are not. They've spent the last three days in a very tight school almost exclusively in the same 4" x 4" x 4" area of the tank, not even venturing out of it to feed. They'll grab any food that comes near them, but if it's even a few inches away they won't go for it. I've been running the tank with actinics only since I got them, but not even the combination of subdued lighting and live food has encouraged them to venture out of their little spot.
So now I'm thinking of adding some small dither fish. I came across a couple of species of eviota gobies listed at liveaquaria that are described as "very active". Anyone have any thoughts on them as dither fish? Any special concerns or needs where they're concerned?
