If you don't mind me asking, why is there ornaments in the tank? Give us some info on the tank like lighting, tank size, how much rock, is the rock live rock or base rock. As well as tank perimeters like cal, alk, salinity, temp, and nitrates.

 

[Bluemon]

Its a 5 gallon dwarf seahorse tank
LOL

when i got the coral it had yellow dead (?) zoos on it also, if that helps

no live rock except the one its on.

 

[Bluemon]

salinity 1.023
ammonia-0
nitrite-0
nitrate-5
temp-78

You should dip it in something like a lugols solution. How old is the tank? How long have you had the frag?

 

[Bluemon]

i already dipped it in iodine when first acclimating.
tank: month
frag: almost a week

Are the other polyps opening good? If they are then the brown ones may just die off from stress.

 

[Bluemon]

the other ones are finee

Is that freshwater? JK you need some LR in there, what kind of filtration do you have?

 

[Chris Lakies]

What kind of substrate? Looks like FW pebbles? I would get rid of the plastic plants and change substrate...im assuming ur lighting isnt up to par?

Sorry, but I'm tending to agree with the theme above. This appears to have been a freshwater tank, the water was dumped out, and saltwater was added. There are quite a number of issues from possible old contamination (ammonia, phosphate, copper), not enough rock, likely lack of filtration, freshwater substrate, etc.

It would definitely help to have more info, but my hunch is more research and reading will likely be in order before you attempt more corals.

 

[Bluemon]

1) It was never a freshwater tank, and the substrate is tahitan moon sand
2) i didnt need that many rocks (or none) for my dwarf seahorse tank

Weird, my tahitian moon sand is black.

What is lighting and filtration?

Hi Bluemon,

Your last post answers all the questions ask.
This was my first saltwater tank,
However, I
modded the hood to accept a more powerful light and fan
modded the filtration
added 3- 1in x 1in 60 gal per hr pumps in the tank for water movement
added lots of live rock

The live rock is your source of bacterial growth for continued tank health;
The filter is helping with oxygen exchange;
For seahorses you don't need water movement, but for corals you will;
For seahorses you don't need more light, but for corals you will.

I assume the tank is great for seahorses, but as it sits, will not sustain corals. If you do some modifications, it will.

10w CFL is probably not going to be enough for them.

 

[bobbychullo]

10w CFL is definitely not going to be enough for them.

ftfy :spin2:

 

[Bluemon]

They are doing fine now.
Thank you guys!

Weird, my tahitian moon sand is black.

And it's pretty fine from all the descriptions ~.5-1mm or so. That looks like 4-10mm gravel.
