I bought an Orange Linkia about 2 weeks ago and it isn't looking good. I have a 55 gallon tank with a Blue Linkia and a Green Linkia. They both are doing fine.
Could you give us some more details about your sick fish? We need to know the symptoms, and also information about your tank and it's water parameters. (ie: ammonia, nitrites, nitrates, pH...) Is your tank cycled? There are many things that can go wrong in a cycling tank, but there are also illnesses your fish could be suffering. If we could have some more info I'm sure that everyone will do their best to help you out! Good luck.
My tank was set up the last week of July and it is 55 gallons. My last water test which was a couple of days ago were;
pH 8
Ammonia 0
Nitrate 10
Nitrite 0
Temp is 79.5
My last water change was on August 31.
I have live rock and live sand. I also have a blue linkia star fish and a green linkia star fish. They are both on the small size and are doing great.
My orange linkia is probably twice if not three times the size of them. The lfs owner said that it was the largest one he had seen as far as orange. It was doing good until about 3 or 4 days ago. Then it quit moving around the tank and when I felt it, it had a soft feeling to it. Also, it has a wrinkled texture to it.
