Pix & ID: Critters that come in your rocks: the good and the bad.

Need more info. Does it move around the tank or is it stationary? If it's stationary, my guess would be a tunicate. If it moves around, maybe some type of cucumber.

It seems anchored to the rock. It expands and shrinks and leans left and right. It also has a shrinking response if I move my hand over it (causing a shadow). It is probably ~ 3 inches when shrunken and 4 when expanded. At first I thought it was a piece of the rock until I noticed movement.

When I googled tunicates I didn't see anything that looked like it but I know that doesn't mean much.

Yeah, it's a tunicate. There are so many that it's not likely you'd find a pic exactly like it.

Thanks! I'm guessing the prospects for long term survival in my tank are not good.

 

[SushiGirl]

All depends on how much there is in suspension for it to eat. I've had little ones last years, I've had larger ones like that not last long.

Corals?

Corals?

I acquired 4 rocks form friend who needed to clear some space in his tank. All of them seem to have some kind of corals. What do I all have here?

1. ?
2. palythoa or zoanthids
3. looks kind of like a sponge
4. hydnophora

1st one may be snake polyps, middle 2 are too blurry to tell, last one is some kind of encrusting SPS.

Diatoms or dino?

Diatoms or dino?

Help identify please. These algae seems to receding when lights are off, and shows up like crazy otherwise; which makes me wonder whether this is dino.

Apologize if image appear large. I couldn't figure it out how to resize from phone.

 

[SushiGirl]

Algae uses photosynthesis. Could be dinos if it's stringy & snotty looking.

IMO it doesn't look snotty at all, thanks!

 

[Sugar Magnolia]

Looks more like cyanobacteria to me. Are you using RODI? Running any GFO?

 

[SushiGirl]

Could be cyano or diatoms.

 

[adityaw]

I use RODI and been running GFO from the beginning, phosphate register 0, but trate at around 5. I had purple cyano so I used chemiclean which wiped them. But as you can see my sands are still brown, that I hope it's not dinos. Is it possible that even when tds is zero silicate still there? I don't have a test kit for them. And it's impossible to get the kit around here.

 

[SushiGirl]

Silicate is usually in the sand, not so much the ro/di water.

Hey All,
My gf just recently came into possession of a new snail. It was given to her cause it and another snail weren't getting along in her mother's pico tank. We believe it to be a Cowrie snail but are uncertain on the specific type. Can anyone offer some assistance. We're checking a bunch of sites for id help but can't find any close enough. Thanks in advance for your time and help
