Identification?

[Robert59]

Got these and forgot what they called and why one is doing good and the other is not doing good trying to see what height they like and water flow? Love this hobby just learning and asking lots ?also coralline good or bad?

I'm not really sure about the first picture, (maybe a Laptastrea) but the second one is a Goniopora. This unfortunately is not one of the easiest corals to keep. Definitely do some research regarding the care of this coral. Here's a couple links to get you started. GL.

Hey cloak thanks I'll check it out

What you have is called red slime. it's a pest bacteria. see this link to I.d. and treat: http://reef2reef.com/threads/cyanobacteria-questions-answers-and-solution.253823/

Oh yeah, the first one looks like leptrastrea to me.

I bought a Green Goniopora months ago and it didn't last a month. One of my first failures. It became covered in brown slime (bacterial infection) that eventually destroyed it over the course of a week. Since then I have asked a number of breeder/sellers at swap meets if they are hard to keep. I received a whole variety of answers. "I've never had luck with them", I've always had luck with the green ones", "The red ones are less hardy than the green". "The reds are easier than the green". .... you get the picture.
Cloak, Thanks for the link! I'm going to read up on this too.

Coraline algae is very good

So what u r saying they are the same but the Reds r harder to keep

 

[RJinPV]

Yes just to be clear the second one looks like the first Goniopora I had. My light was 2 T5s with a Ecoxtic marine LED strip. I put it up high (rookie error) then moved it to sand a few days later. Then it developed the infection.

Green is harder to keep, Red Goniopora is often aquacultured.
I see a lot of cyanobacteria which can be problematic for corals placed in the sand bed.

The pic there is cyano but on my rocks and in my sump pump it's a red hard crustaton in my refuge

I really don't know. All I have is anecdotal statements from a bunch of different breeder/sellers that contradicted themselves. That's why I like this R2R community. There's a lot of people here with lots of experience.

Having said al that I recently bought what the seller claimed to be a red "short stemmed Goniopora" at a swap and it has been doing well. I don't even know if that species exists. I just looked up leptrastrea and what I bought looks a lot like that

 

[Robert59]

My green goniopora is doing good go figure and the cyano I just a cuc for that and they r hard at work

Green Goniopora will appear to do well for months and then the slow decline begins. In the 90's we called them rent a corals.

However there are a lot of hobbyist that successfully keep all types of Goniopora.

It's thought that the reason this corals does poorly for some hobbyist is a nutritional deficiency. There are specific foods you can use such as Goniopower. DOC/dissolved organics maybe of benefit to this coral, instead of striving for an ultra low nutrient system/ULNS consider keeping low level nitrates and phosphates, long story short do not over polish the water.
