A big spot on my puffer (and it's not a spotted puffer!)

Thanks for the opinion. How long did it take for the spot to heal?

I'm feeling kind of bad now, because I have this type of anemone that I guess it like a weed, but I kind of liked it (hey dandelions are pretty too when they're not on your lawn ) so I left them be. Some of them have gotten quite huge.

Which leads me to another question... I'm still not clear on 'what' type of growth is considered good and what isnt. You see the red growth on the gravel in the picture? Is that considered 'live' now? Is it the type of growth you want? Again, I think it's rather pretty, but then I read about 'the terrible red algae' and I wonder if that's what I've got. Same with the algae.... I have all this long algae growing on the back wall, kind of like the coat on a golden retriever (or maybe not golden) and it sways so gracefully in the current. But is it a bad thing???

Sorry if these are stupid questions!
