• Mollusk (tridacnid :) )

  • Johnny

Colleagues, please help with resources on filter-feeding mollusks. I feel like I'm searching in the wrong direction (I've tried various parameters, even like a tridacna, sl tridacna, and others). I have a stone with tubastrea. The bottom is almost flat and chipped, while the top is a hemisphere. In the middle, there's a pattern resembling a dried tridacna. I placed it in the aquarium and started "feeding and stimulating" it. After a couple of days, the coral began to increase in polyps and produced small new "offspring" nearby. A week later, I noticed that the stone, with the "tridacna-like" pattern, had opened up by 2-3 mm. I thought maybe I had pressed it too hard when placing it on the live rock. Another week later, I had to move the coral. I noticed that the crack had disappeared and closed up. I decided to keep an eye on it. In the morning, the crack was back, and I could see a milky-colored mantle inside. I shone a light on it – the interior looked like something resembling a comb, ciliated, about 1 mm thick. It reacts to light intermittently – sometimes it closes, and other times it just slightly reduces the gap. Sorry for the photo, the angle is really awkward, and I can't press the phone against the glass. Has anyone had similar types of mollusks? What did you feed them? How long were you able to keep them? (What was in the system after their death?) Thank you!

Often, live rocks (J.K.) are brought in. It resembles an oyster the most (attaching itself to the side of one of the shells). It feeds as a filter feeder. The lifespan depends on luck. The conditions for keeping it in an aquarium are quite tricky.

Did they die in large volumes or small? What were the consequences for small volumes?

Cindy

Why they died right away. Some are still alive, others were eaten by their neighbors. None at all.

Yarik, I had a huge problem with this mollusk... I bought a decent piece of tubastrea. There was this mollusk the size of a fist. And just as I went to Illichevsk to relax for 3 days. Upon my return, I was in complete shock. This mollusk had died, the water was cloudy, and it smelled. Ammonia levels were off the charts. The tubastrea had almost completely come off, and all the others were shriveled... I started to wash out and identify this mollusk; there was so much dead flesh that it could probably be compared to the death of 2-3 fish. So, it's not that simple... The tubastrea was slightly smaller than 2 fists.

Of course, if there is half a kilo of rotten meat in a small volume, the consequences will be accordingly.

Max, got it, thanks. Off-topic. Anyway, tomorrow I will be selling oyster meat at the flea market. Get in line - the offer is limited.

Jeremy

It's a pity. This set - tubastrea is a more complex object than an oyster.

Tubastrea is generally not a difficult object. Yarik, don't cut it out on purpose. You can make a mess. In your scales, it doesn't pose a threat to you.
