If interested... a good read... Should I buy that fish - is it healthy? http://www.reefsanctuary.com/forums/fish-diseases-treatments/34036-should-i-buy-fish-healthy.html
I agree with that post most people really dont think. Thinking long and hard about what fish, inverts, and/or coral aquarist plan to add to the system is a big part to keeping aquaria. I see it all day everyday at Petco. You can preach all the time about QT but i think im right to say that people wont learn they're lesson until Ich, Fungus,or other bad infections infest they're tank.
Thanks ! I enjoy sharing with the RRMAS forum some of the best links, that have helped me along the way in my saltwater journey.
