• Parazoanthus have decreased in size...

  • Karen1649

Earlier, the parazoanthus were large, about 2 cm in length, but now they have become small, up to 1 cm. Has anyone experienced this situation??? What should I do?? What might they not like?! Maybe they need to be fed something special?!

Cynthia

I don't think so. Can you remember what you did in the aquarium after they started feeling unwell? 1. Changed the lighting. 2. Changed the current. 3. Rearranged them. 4. Water changes, cleaning, feeding, etc.? Do you have any photos?

Catherine

It seems like nothing has changed, the current is blowing right at them, the light is almost 3 watts per liter, water replacement is almost 40% per week, I feed them with this stuff a couple of times a week, I've been feeding them for over 2 months but I don't see any results! pH is around 8.3, nitrites and nitrates are almost zero... I'll try to take a photo!! Also, they used to be brown, but now they've turned completely yellow!!!

They are all doing well. And especially now.

Antonio

So what about them??

Brandi

They should be yellow. 40% a week is cool, just like 3 watts per liter. There is no need to flow on them, and you shouldn't feed them individually.

So how are you doing today, what have you changed in the aquarium after the suggestions, how are the Parazoanthus doing?

I moved it to a quieter place! The picture is still the same!!((

Stop feeding completely, place in a non-bright spot, and check the salinity with several hydrometers.

Yolanda

Who can I visit to test my hydrometers???? Preferably tomorrow!! I'll bring beer!!!

Michelle104

You can drop by, just call beforehand - anything can happen...

I have 2 hydrometers - one shows 1.022 (float type), the other shows 1.023 (dial type), for some reason I believe both!)) I trust the float one because I bought it from a reputable source, and the second one because I bought it a long time ago from a person on a forum, and I used it for over a year, everything grew and was great! The only thing that keeps growing and doesn't complain is Aiptasia!!

, I will signal the sage!!

Under such lighting, "almost 3 watts per liter" the umbrellas should be pressed to the ground. If there is not enough light, the umbrellas stretch towards the light and puff up their heads. In my opinion, this is a lot of "almost 40% water change per week" unless the water is from a well-maintained, working aquarium.

Denise

No, I have a 25-liter jar! I fill it with clean prepared water once a week! But they haven't just decreased; they have even stopped reproducing! Before, new ones would appear, but now it feels like they are lacking something for their development!

Robert800

I have Parazoanthus on the upper rock in the center of the aquarium, about 30 cm from the lights and 30 cm deep, growing in an open area where the flow from two pumps directed at each other meets. I do not feed them anything. They live and reproduce; from 13 polyps, there are now about 30.

Gregory

By the way, a question, what if they are lacking oxygen???? Could that happen??

Melissa3200

I've read a lot already... Everything has been written above... Let's think. The pigmentation of parazoanthids is yellow. Depending on the NUMBER OF ZOOXANTHELLAE, they either "mute" the color with their quantity or, conversely, when their number decreases, they "reveal" the color of the coral. Oxygen is only needed at night and in minimal amounts, which can be effectively managed by the flow from the pumps. Don't read scary stories at night!!!
