Almost all fish stores copper there fish only tanks as well as a lot of public aquariums with fish only displays as they cannot afford huge losses.

My 15 gallon tank seemed perfect though and my blue tang never seemed to have a problem. My yellow tang as of now doesn't seem to have any spots and the tank seems back to normal. Of course, I don't know that for sure though.

So should I just leave it with the 5 fish I have now? I do have 5 snails in the tank too.

And again, because I just wung this from the beginning, I have no idea what tests I should be doing and what kind of test kit to buy. I have always done my water changes though. What would be my best option? Also, Is my yellow tang suffering in any way by being "cooped" up in a 32 G then?

Thanks for all the advise. This site is great! And I would like to assure the guy wondering if I am some fake troll account trying to do something extraordinary besides obtaining advise on fish, that I am absolutely real and that I really really do just want fish advise!!!

How big are the tangs?

Welcome to Canreef. What are all the types of fish you have? The tangs need to go for sure unless they are really small but even then they will need a bigger home down the road. As for testing for starters you need to test for Nitrate, Ammonia, and Nitrite.

Tangs need lots of swimming room, a tank that is 6 feet long is an ideal home for this type of fish. IMO a tang should not be in a tank less than 90g.

Shyte!

My yellow tang as far as I ever thought is quite small. About 2 inches long. The blue tang was about the same size and did grow a slight bit over the year. And like I said, the blue tang never did seem to have a problem in that small 15 gallon tank. I also have 2 clowns and 2 B/W damsels. 5 fish in total. One cleaner shrimp, and 5 snails.

Also when I first started the hobby, the guy at the fish store said I should only keep the damsels for a short while because they will get aggressive. They did seem a little aggressive at first but they all seem to get along now. I tried to give them back to the store but they wouldn't take them. I kept them because I didn't want to kill them. Should I really get rid of them still and if so what could I replace them with? Should I just keep my yellow tang and hope for the best?
