Since this is a thread about clowns and anemones I figure why not share my nem / clown experiences. As many of you know, I have a very large (at least 12" diameter) Haddoni (Green Carpet Anemone) in my 120. This monster is both a highlight and a hazard to my tank.
First of all, it is an absolutely beautiful creature that my clowns practically worship. They lie in it, cuddle it, use it’s folds as hiding places and safety spots, etc. Those interactions are probably the most amazing feature of my tank. There have been plenty of times when I thought seriously of removing it from my aquarium, but my family absolutely loves the interactions and have objected strongly to any thoughts of eviction. And, in the end, I think they are right.
It’s also super cool that I’ve had the guy for over 2 years now, after buying him for a song from Christian when he broke down his 300g set up and moved to Florida. My original 90 was barely 3 months old when I added him, which is crazy if you read about carpet anemones. It bleached and was bone white and somewhat sad for months. But it recovered and I’m quite sure it’s grown at least an inch or two in diameter in the meantime.
Ah, but the cost. They main cost has been “fish eaten.” In particular, wrasses seem unable to avoid landing in it. I simply stopped buying wrasses for my tank after around 7-8 of them wound up in the nem, some of which cost me in the vicinity of $75 (argh!). It’s also eaten a copperband, pretty sure it got my engineer goby recently, and a few other fish here and there.
The big advantage of the carpet, over say the BTAs is that it doesn’t move much and it doesn’t split. I basically created an area for it and pinned it in there with rocks. Of course, if it really wanted to, it could get out, but my experience has been that it doesn’t move from it’s comfy spot.
Here’s a pic with the clowns to honor the greatness of the Haddoni.
