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

Help me God

Help me God

I am a complete newbie, I read the forum and visited a couple of fishstores .
I have 2 FW tanks with tropical fish and cichlids. I like testing water and PWC. I don't eat until my fish eats.
I am very happy since I got fish. Seriously, happier than I ever remember.
Usually I'm quite down during the darker months.

But I was getting envious of corals, the movements of SW fish, and especially their personalities (not colors).
I feel bad that I'm betraying my FW fish.
But I bought a 20g Nano SW tank with 2 Tomato Clowns and a lot of live rock on CL. It has some polyps and of course to me it looked all amazing, compared to my simple plants in FW:headwally:

So I transported that thing 39 miles 1 way. in my car.no water loss w/3 buckets. It looked scary ; I remembered the crab and stopped rearranging the sand in the mud w/my bare hands. asked hubby to keep the flashlight on the crabs so I won't crush him.
I couldn't see the rocks, let alone fish, that I was putting there b/c of the dirt at 7pm and at 2am is was clear. I went to sleep happy.

Now 3 days after the move the emerald crab dies, I think it wasn't the molt.
I drop everything, pick my 4 yo and go to LFS to get water for the 5g PWC.
My skimmer is full of foam too- not good news.
I did rearranged the rocks with many hiding places which Clowns divided immediately, but I don't hold hope for the crab.

It has been ok since then,but I haven't seen the crab for 4 days... how did I kill him? I tested ammonia 0. I need to buy API test for marine.
I added all the Kent's additives today as Sat will be a week since I own the tank.

Please, don't think that I'm a moron, I am very excited and love to learn.

I knew there are some critters in SW tanks, but I didn't expect such a variety and didn't even think of a possibility of them being poisonous or stinging me.

I always put my hands in water b/c I like it (I like planting without gloves too), now I will wear gloves.
Also I will forgo anemones and Zoas no matter how pretty as I have kids.

I realized that I am in for quite a eye-opening experience.

I have 1 question : there are some black moldy spots appeared on 1 of the rocks, pea-sized the most. I looked at 1 under 20xmagnification, it looks like a few dark brown snails/shells. It dried up fast in my pocket (I know...)
WTH is that as I scraped it of with my nail?

I have 2 Turbo snails for 2 days now, but it takes longer for the eggs to hatch and they have been exclusively on glass. 1 is active,another doesn't like to be touched- goes immobile for hours.

I have a very good eye when it comes to animals/bugs (so bad I am that I could never see the mushrooms in the forest, only critters), I notice all the changes,so I hope I'll catch the problems at the very start.

I clean the glass inside daily. I topped off water twice w/RO FW in a week.
What else should I do?

Is this new growth dangerous for corals/polyps/fish? :worried:

Also I was told to use daylight T5 for 3 hrs max or I'll have green algae.
Tested one day- got algae, scrubbed off. I don't freak out, I act.
Now I think 3 hrs is low-light conditions, shouldn't it be 7-8 hrs? :hmm4:

I still hope to get Blue mushroom to grow as they should be OK with low light.
I don't need anything fancy, I want something that will work in my setup.
Anything that looks like coral is fine with me. anything alive will work.

I need QT as well, have an empty 15g.
I love this hobby - no time to shop for clothes and toys for kids-
hauling buckets of water and testing and scrubbing; actually should
save our family some money. who could have thought...but I'm happy.

Thank you for your help.
 
Found this guy swimming around today. ID would be great if y'all don't mind

Hope these are OK to remain as they're cool! :bounce1:

Hard to see from the photo but the top one is the colour it appears and disappears deep in the rock with no visible parts, the bottom one is much more pink in colour and disappears into its own tubey thing...
 
And this, is an anemone? Maybe? My guess is it is a non-photosynthetic anemone.
