I would like to update an old thread. My tank, (I can't really call it a reef again yet) is doing fine. I did npt replace the corals yet and I have found out that it was Zinc Orthophosphate which killed my corals. Apparently my RO membrane has some problems with orthophosphate and my town really likes to put it in the water so I have to re figure my intake water.
As I said, this has happened three times so far, each time there was about ten years in between.
Anyway it turned out to be a good thing because I am getting a lot of time to experiment and it would not be good for the corals.
I have 15 gobies, 12 different types. Out of the two pairs I have one pair is mating (I think because it takes place in a bottle) I have another pair of green clown gobies and a pair of yellow clown gobies but one of the yellows is trying to mate with a green one. If that works, maybe I will get purple gobies :redface:
I have always thought captive fish do not get enough vitamin A and D so I am trying something on my hippo tang. Hippo's, after a few years always seem to get HLLE. So far this one has not gotten it but I have had many of them and it seems that they all get some form of the disease eventually. Mine just has tiny spots of missing blue on his face which is where it always starts. He is getting large doses of the vitamin every day. I looked up my old notes and saw that I once cured a large french angel of HLLE by using vitamin A. As you know, French Angels are mostly black and the disease really makes them look ratty. After a couple of months his skin was completly healed.
That was one fish 30 years ago so I can't make a statement as to the benefits of the treatment so I figured I would try it again.
After a couple of weeks the only thing I notice is the fish is "bluer" but I am not sure yet if it will make a difference in the slight white spots on his face.
I feel fish are lacking in Vitamin "A" and "D" because fish in the sea eat mostly tiny fish which are loaded with those vitamins concentrated in the liver. The normal aquarium foods are severly lacking in this.
Time will tell.
Have a great day.
