Do you guys keep any emerald crabs in your main display? I have one and so far he's been good. Any bad experiences with them?

I had an aggressive one and searched RC to educate myself. Emerald crabs are generally safe but as they get bigger they can be a problem. Can be pretty hard to catch as well. I wouldn't get another one of those.

Thanks. Mine is pretty good/tame. He comes out and looks at me all the time. He's not afraid of me. He also leaves the fish/corals alone as far as I can tell. He never comes near my hand when it's in the tank, but doesn't shy from it either. I've had a few but they have all died except for him.

Can anyone help identify and tell me if this thing is bad? See attached photos. Photos are bad, sorry - its tough to photograph but it when it moves it looks like a snail without a shell.

It has the same antennae / feelers as a snail. It does look like it has a thin shell but not a thick snail shell.

I've recently had a monti digi which looked liked it was attacked by a pest so wondering if this thing is the reason.

Thanks for any input or suggestions.

Good luck. If they have enough algae around, they'll likely leave the other stuff alone. Mine was a good size about 1inch body size. I suspect the smaller ones are fine and when they get bigger they start looking for other food. That's just my wild untested theory...

From description it sounds like a stomatella snail, which are harmless and beneficial. The pics are weird though, as if maybe only the shield shell is pictured. You should google stomatella snail and compare

[agranoff]

Thanks for the reply. I think it might be a stomatella. It looks similar. I tried catching it the other day but it moved quick. I will leave it alone for now since it sounds like it is a good thing.

Found a couple of new things in our tank, though they where new coral things growing but now not sure, please can you tell me they good or bad.

It looks like hydroids in picture #2.

Picture #1, clove polyps perhaps? Something along these lines anyways. (see link below)

Couldnt get a good photo of this guy. He was the length of a fingernail, pink/peach looking color. One end of his body was like a clear white color? In my bad photo you can see the white part of his body towards the top of the tank. He was swimming all over the place and would stop at my live rock like he was trying to burrow and then was swimming again and he made it into my filter..

Polychaete epitoke?

[RalphTheOscar]

Are those good or bad, and because he went into my filter will he die?

[Cdogsailr]

Since it's now disappeared into your filter I would classify it in the genus "toast"!

[h2pvnus]

What pods or bugs are they. Harmless or bad. Thank

[SaltyTony]

Can someone ID this possible slug/nudi that I found in my DT? Thanks

I found a bunch of these little snails on my sand as the lights were going out. And found one on my lobo. Any ideas what it is?



I've tried to find anything that resembles it in hitchhiker guides but haven't seen any. It's very tiny and is dark brown/black and almost looks like it has a slight spiral shell. Only snails i'm supposed to have in my tank are astrea, cyrith, turbo. I do have collonista and stomatellas aswell.

[SaltyTony]

Thanks for the ID Sugar Magnolia. I will be evicting him from my DT.
