Magnificent?

[Delphinus]

Very nice. Just a warning though, you're going to have problems with him wandering right up the rockwork or worse yet the glass.

There are two strategies you HAVE to employ with this species to keep them rooted:

1) They want to be at the top of the reef (which is where they inhabit in nature). If they can sense a path upward, they will move in that direction. As such, they need to sit on a bommie (fancy term for "rock pile" or "column" but look it up for a few examples of what I mean). It's imperative that any direction away from their spot leads down and they can't touch any neighbouring structure that's higher.

2) They are light greedy. Even though what they have may be "enough" to sustain them, they need to know they're in a spot where they get the most. So the best strategy here is to place the bommie from #1 right under a halide. This way they're in the "hot spot" and any movement away from this spot takes to a spot of less light.

I kept this anemone for 8 years and never had a problem with him moving. Although in the end, in a fit of frustration I sold him (it's really hard to do ANYthing with a tank that has a 24" anemone it). Which brings me to my last point - be prepared for massive growth. The one I had was 6" when I bought it, and 18" within, uh, about 6 weeks if I recall correctly. He settled out at 24", which is sort of the reason I ended up with a 30" cube - it was the smallest tank I could do where he couldn't touch the glass from anywhere within the tank - even in a standard 90g tank I had problems with him finding the glass and then deciding that was a better place to be.

Oh and one last cautionary note - handle them very minimally. If disturbed they can release a lot of nematocysts, which you can't see: but will kill off an entire tank of fish within minutes. I had at least 3 complete tank wipeouts everytime I needed to move mine. Nothing can prepare you for that emotional shock of seeing every last fish (except your clowns which are immune) drop dead like that.
