The Pinaple sponge look like this:

Your picture is not clear to me. Might be a variante?

I think the first one definitely is a pineapple sponge, the second picture doesnt look like one but may be the start of one possibly.

[themagicman]

What your seeing in the second picture is a whole different type of sponge altogether.

Would you happen to have an idea as to what kind it is do you?

Any one know where I can get my hands on some asterina starfish?

Depends on what you're on. I'm using a phone or an iPad and typically there's a paperclip icon and select a photo from your gallery. Or you can link a pic from imigur.

It look to me like a small Jellyfish, possibly Cladonema family? Normally not a problem, should go away by itself. In large quantity may be a problem, but a few should not. Is your tank fairly new? In my experience, I got those in the first few month after starting a new tank.

Hope that help.

Any idea on if these are "good" or "bad"?

I think they are just asterina stars, which are generally considered OK?

You are right! Always ending with some in my sump, rarely in my display. Not a problem unless you have tons of them.

I don't trust them. They don't really do much for a tank either. Your basically just left with a starfish that multiplies rapidly and has been known to eat various corals on occasion. It's not worth the risk IMO.

It's fine. Probably won't last long. It filters out the water.

Hi All

My tank just finished cycling and I found this guy in the sump. Any idea what he is?



Here's a video of the way it moves too: https://www.youtube.com/watch?v=27PxQgai_cE

Anyone know what this is? I found it in my overflow. It kind of pulsates and almost looks like little critters are moving on it. Should I remove it?

It almost looks like a rock flower anemone to me. But it's really not a good photo.
Pull it out and put it in a shallow bowl with some tank water and then take a couple of pics. It will get you far better results.

Regretfully, I don't have a photo yet. But I've been searching for an I.D.
I have a beautiful, huge sun coral that has a small bare spot. When originally purchased, that bare spot had a tiny spot of, what appeared to be, red coraline algae. Within weeks it has gone crazy with growth. It is red/burgundy in the daytime lights, but turns grey/Green when the dusk/dawn lights come on. Today, when I touched it to feel the texture, it changed color immediately. It's awesome, but it will consume my sun coral, I'm sure. Any help is appreciated!

[deputydawg88]

Any idea what this guy is and whether he's safe? I'm assuming it's some kind of sea slug or nudibranch.



And what about this guy?

I found him in my sump but he has since disappeared, no idea where to. I haven't seen him for a few days now.

Top is a harmless Elysia slug, the other is a harmless bristleworm.

It looks like you might have an Aiptasia right in the middle of that Blastomussa coral.
