Ritteri help

[Delphinus]

IME they can be very restless like this.

I kept this species myself for many years. I found to keep them rooted in one spot, two things were needed, but both really come down to the same "hunger" for light.

1) They like to be as high as they possibly can on the reef work. If they can sense a path to a higher location, they'll likely take it. As a result, the best perch so to speak is a column or "coral bommie" far enough (so that not even an occasional brush against was possible) from the glass and any neighbouring rockwork that might be higher.

2) They want to be as close to light as possible. A point source light really helps in this case because it will create a spotlight effect. Once they detect they're in the spotlight, in such a way that moving away from the spot puts them into less light .. they'll stay. I found that when I ran halides and had 2 over the tank .. if the one over top of it didn't turn on, it will wander over to the side with the light within hours. Turning that light off and putting the other back on, drew him back like a magnet. This happened enough times that it was no coincidence.

As for feeding, I generally fed mine mysis. He did eat rather a lot of it, come to think of it. Probably every day food was consumed. (Other things that did well were any kind of shrimpy food - shrimp, cut pieces of prawn, krill, mysis, etc.)
