strange

And should i be concerned?

So I got an Anthia's and two clowns the other day, as I said in a prior post. This morning when I turned on my tank lights the fish came out as usual. I stepped away briefly to go grab some food for them. I come back to see the Anthia's hanging out with the Clownfish, and be puffs his fins up...

I have had this brittle starfish for awhile and I was wondering if it could be identified. It is different from any other brittle stars I have kept, in that it has spines on the body as well as the legs.

While cleaning my sump/refuge, I came across an odd growth on some coral rubble I had laying down in the sand, the growth was growing into the sand, and under the rock was quite a bit of debris and waste that settled there. I am not sure what it is, though it is hard, like an sps, and it looks...

Hi guys something strange is happening. I originally bought 10 red legged hermit crabs and a couple days ago I noticed that one was replaced with a cerith snail. I thought maybe there was just a mix up at the store but today I noticed a second cerith snail. I didn't buy any of these snails yet...

Hi again, well the tank is up and running. I'll be posting pictures at a later date. Have something unknown growing next to my shroom. Was wondering if anyone here could throw some light on it please? It's the small flowers & the cue tip little green ball.

So i was moving my rock around to try find my wrasse (who vanished, believe my bristle star ate him) when i noticed this thing sitting on my sand bed. I didn't know what on earth it was and removed it from the tank. Is it a sea cucumber? i don't know what else it could be.

Hi there everyone. I am new to this forum. I have had my saltwater aquarium for about two years now. We have two percula clown fish and a dottyback as well as many snails and crabs. We recently decided to try some corals. They have been in the aquarium now for a few months and are doing well. I...

I was just watching my tank for a bit just before and i realised there are tiny little white specks on my glass. There too small to take a photo of though. There about the size of a full stop on this page. I think they might be a species of pod? Or are pods too small to see with the naked eye...

Please enter your "strange aquarium events" into this semi-official PMAC log for the strange events. Ok, I needed to keep a log of all the odd things that have happened as the result of keeping tanks (and not the mysterious lack of funds in the bank thing). I have had some odd things happen...

Was bored at work and started googleing tanks and found these....

I bought a pulsing zenia a few months ago. A strange pink with tiny purple bumps "bubble" is growing next to it and growing quickly. Any idea what it is? <!-- / message --><!-- attachments -->

Hi I'm hoing you can help me. I'm fairly new to this hobby and my first coral, a mushroom, has been doing some funny things since i've had it. There are 5 mushrooms of the same variety on the rock which I purchased but only one is doing these strange things. It starts to close up now and again...
