My First Tank

[TANGOMAN]

Welcome to the world of endless expense. Equally endless enjoyment, provided things are goin' good. I have little experience with your prospective fish. I have read that Regal Tangs are "planktivores"? Others with experience may be helpful with feeding/nutritional requirements. Those nutritional requirements are critical for life in captivity.
I am a big supporter of quarantine practices. Many aren't. They both have benefits and drawbacks. A 10g is small IMO for a quarantine tank. Rapid fluctuations with so little water. Fluctuations are the last thing a stressed fish needs. 33g's are available from Gold's Aquarium for I think $30.00.
This site is a valuable asset. There are a lot of knowledgable folks glad to help. As mentioned, patience is a must. So to is the ability to overcome the fear that accompanies asking what one might perceive as "a stupid question". Don't worry, I've already asked all the stupid questions.

ps when ya' find the good stores in town, let us know. You'll be king !
