Green Haddoni Carpet Anemone

My Haddoni is by far one of my most favourite creatures in my tank. About a year ago I was visiting my favourite aquarium store here in Finland and there was a large Clarkii Clownfish that had been traded in because she’d gotten super aggressive. I, of course, was fascinated and really wanted her (She’s now Big Boo) but I saw she really liked the Haddoni that was in the tank with her, so I decided to get both (and eat noodles the rest of the month hah).

When I first got him. He’s grown a lot since then.

Anchoring Spot

At first, it was tricky trying to keep the Haddoni happy. I still had my old lighting (two Fluval Marine and Reef 2.0 lights), so I wondered if that was causing problems. The anemone went for a wander (quite a thing to see) and landed in my power-head but luckily was so big that was only slightly damaged and healed quickly. I soon found out the problem wasn’t the lighting, the problem was feeding.

FEED ME!

Feeding

It’s a quite big carpet anemone, I didn’t realise what size of food it needed. Once I started feeding it prawns about twice a week, the anemone quite happily settled down in the same spot and stopped wandering about.

Getting comfy in its favourite spot.

Moving Tank

I moved my whole reef in March 2020 to a larger system. I’ll write about that in another article and link it from here at another time. I purposefully left the Haddoni till last as I wanted to take my time and make sure I had a good spot for it in the new tank.

Then disaster struck. As I lifted one of the rocks near the anemone, I didn’t quite realise that the anemone had attached itself solidly to both the rock and also the glass at the bottom. I lifted the rock a bit too hard and damaged the anemone. It looked bloody awful.

Death’s Door

There seemed to be what looked like an air bubble trapped in the anemone that was forcing part of it to float straight up in the tank. It looked really freaky and I’m not ashamed to say I shed a tear for my poor Haddoni. The foot had a tear in it which looked like spaghetti. I didn’t think it would survive the night and went to my local fish store for more carbon just in case.

The next morning the air bubble was gone and the body part was no longer floating, but the anemone was about half it’s size. I moved a rock slightly that was near it and it deflated and was a pitiful sight. Its mouth was also gaping open a little although I didn’t see its insides coming out. I really didn’t expect it to live.

Healing Days

I moved my tank on Friday the 13th of March (figures!) and so far the anemone is looking a lot better. He’s puffed up and large again and has been eating like a horse. I have been feeding more often hoping that it’ll give it the energy to keep healing.

Today I removed one rock from in front of it so I could get a better look. There was some kind of plastic-looking coating that is shedding off from the area. It doesn’t look like the anemone sloughing off bits, but more like a scab that’s come off because it isn’t needed anymore (wishful thinking maybe!). I will be keeping a close eye on the anemone and I’m still nervous about whether it will make it or not as infection is the thing that could kill it and it’s only been two weeks.

Theories

The sand I put in the new tank was clean. I hope that might make a difference whether the anemone would get an infection or not.

Sometimes clownfish being hosted will remove necrotic tissue from their anemone’s and help them heal. Big Boo is pretty obsessed with the Haddoni so it’s possible, but I haven’t really seen her nibbling at it, just cuddling into it as usual.

A bit puffed up and thinking of moving around, hopefully, to somewhere good.

Currently

Today I removed a rock from the front of the tank that the Haddoni was wedged in between so now it has enough space to spread out if it wants. I removed the rock about an hour or two ago and this was how he looked an hour ago. No doubt he will move tonight and I’ll see what happens in the morning.
