Terry,
I am not joking. But first of all, I would like to thanks for your kind response. Second I would like to clarify what I have.
I have 125 gallons fresh water fish tank for more that 3 years. Two months ago, I converted my fresh water to salt water fish tank.
I changed all my fresh water and substrate to salt water and sand mixed with crushed coral substrate. With my new fish tank I am having 1 Yellow tang, 1 Koran angel, 1 Indonesia angel, 2 Damsels, 1 Domino, 1 Maroon, and 2 Percula Clowns. They are all doing fine except angels.
I believed my tank was cycled because one point at time the water in my tank was very high in Ammonia, then Nitrite went very high. But now they are very low. Even my Nitrate is very low too. PH is about 8.1, temperatue is about 80F. Salinity is about 1.023.
Last week my Koran angelfish have some kind of mouth fungus. This week my Indonesia has a little mouth fungus too. So yesterday I put them in 10 gallons hospital tank. When my fishes get well, I will put them back to 125 gallons fish tank. Thanks for your concern.
I will find and buy the book that you suggest. Mean time I wander do you have any suggestion on what kind of medications that my fishes need. Right now I am using E.M. Tablets (Erythromycin 200mg) for use in fresh or saltwater aquariums. Do you think it is OK to use this medication?
By the way, the frozen cube that I feed was Saltwater Multi-Pack.
Thanks,
