I fell into the "Nemo" trap early on. I bought a Tomato clown (didnt have the Ocellaris variety), a yellow tang, a blue hippo tang, I also had a Kole tang (okay, get the Tang Police on me) 7 Damsels (which were fine) a snowflake eel. OOh, I put them all in together, (without QT) and presto! a major outbreak of Ich. Well, right off the bat, the Clown died after 3 days. then the BHT got Ich, then gave it to the Kole. Finally the Yellow tang succumbed. the only inhabitants that remained from all of those, were the snowflake, and One three striped Damsel. Needless to say, I learned my lesson the hard way. I know go slow. After dropping the salinity in the display tank, removing my LR, and Inverts, I cured the Yellow tang of Ich, ( he later died of something else)
I now have added a porcupine puffer. He spent a month in QT. Now I have a small Hummu Hummu Trigger, and a small Maculosous Angel in QT.
I told my kids, that we have to go slow, and we have to get fish that are easy to take care of. Although, I'm not too sure why I bought the Angel, I've heard they can be tough. But, We'll see what happens.
