chocolate star fish not looking good

One of My chocolate starfish is really gross and doesn't look good and its spreading to the other! I can't find anything that would help me I'm scared to loose both of them. 8.2 ph and all other levels 0

 

Well how about salinity? that's surely not 0? With starfish, generally swings in water parameters (salinity, temperature for example) can cause stress and lead to death.

Hard to say when everything is 0.

What size tank, how often are they fed, what are the inhabitants, how long have you had them, how did you acclimate them?

 

The problem with sea stars is that the vast majority in the pet trade are grossly misrepresented as scavengers or algae grazers. Fact is, they are predators with very select diets, and there's not enough information on the nutritional requirements of each species for us to sustain them properly. It also takes several months for one to starve, so the aquarist usually believes it is eating when in reality it is not.

Unfortunately, once they show signs of degradation, it's usually too late...

 

Either the images do not do the situation justice or I can not make out what the specific issue is.

The first image looks like a chocolate chip star with it's stomach expelled, this not unusual or harmful. In the second the star fish merely looks close to the surface.

Chocolate star fish are relatively hardy, but not reef safe and will need supplemental feedings, especially in a smaller systems.

The first picture is of the healthy one, the second I'm afraid is dead now, I fed them shrimp with chopsticks and they would eat. But awhile ago most of my fish died in the tank (55 gal), but at the pet store they said the starfish wouldn't get the sickness the fish got, but the one that died started acting funny a week ago, and he began curling up and one of him legs had bubbled up and the suction thingys disappeared on one leg. I separated the two of the star fish last night, I just don't know what happened, the salinity was perfect.

 

The second one would sit halfway out of the water during the day, I read that they are not supposed to be exposed to oxygen, could that b a reason for his death? And I have had them for two months, in the tank I also have a blue damsel, a yellow tang, I used to have an eel but he ate one of my fish so he has his own tank now, a brittle starfish, and some live rock. My dad has a couple of other fish in the tank but I don't remember off the top of my head what they are

 

You'll need to do water chemistry and post numbers including Sg......
I would say not exposing star fish to the air is probably a good idea, but I have never really had an issue with it.

How old is the tank?

Fish and inverts like starfish are not going to share disease types so, either water chemistry killed both the fish and the starfish or their deaths have nothing to do with each other......

 

salinity 1.024 temp 78, and 0 nitrate 0 nitrite, 0 ammonia, 8.2 ph, I don't know what sg is, do you think the other starfish will get sick as well? he has some of the spots or boils for a lack of a better word on him as well, but he is eating and is very active, i also have a condylactus anemone, i used to have a purple tipped sebae anemone but it died in the tank. I have had my tank for 4 months

 

SG=Specific gravity.

I am inclined to think your tank is still too young for sensitive inverts. Sebae can be difficult to keep even in more established tanks. Even though basic tests look good you can still stock too quickly.

You should post some specifics of your tank such as flow, filtration....size.
