Blue Hippo, although it is susceptible to ich, is to me a very hardy tang, to tell you the truth.
The longhorn cowfish is a cute addition but they do get big. Since the shape is so odd, beginners love to have one. I used to have one. But it poops huge amounts of waste so I got rid of it, along with my puffers, file fish, and others.
For some reason, I wasn't successful in keeping a yellow tang. But the blue tang? I've had it for a year now and it is just happy. A cute fellow.
Nonetheless, I am hoping to get a 150G sometimes after the summer (hopefully, if the Mrs wouldn't nag about it).
