Carpets and mandarin dragonet?

[OrionN]

My pair of mandarin have been doing well in my 320 for the last 1 year. Very fat. I have 1 haddoni, 4 Gigantea and 2 Magnifica in that tank.

Of all host anemones, I found haddoni to be the greatest hazard to fish. One factor is certainly that they are generally on the bottom where bottom-dwelling fish are more likely to bump into it. But I think another factor is that the tentacles of haddoni are so short that many fish don't see them as the threat they are. Waving tentacles of other anemones are a more obvious thread.

Aside from some panicking gobies and jawfish, I didn't lose fish to giganteas over several years. But I actually lost quite a few fish to haddoni in a short period of time. Even a bluestripe pipefish who normally know how to navigate reef anemones.
