Nothing happened. Everybody seems happy so far. Nobody pays too much attention to anybody. At this point they have different behavior In the tank. The neon dottyback spends most of Its time hunting In and out of the rockwork In the bottom third of the tank and the purple pretty much hangs In the water column In the right corner of the tank, a trait which would annoy me if I only had room for a few fish. Things may change as the purple gets more comfortable in the tank. We shall see what the future brings. (hopefully no pestilence from my reckless behavior) Oh, I added a yellow fang blenny at the same time, an interesting fish which spends most of its time hunting the surface of the rocks, but rarely inside the rockwork. It swims in a halting fashion stopping to inspect something on the rocks and then picking it off. So far it hasn't taken any frozen, flake or pellet from what I can tell. All's good in the neighborhood
