pH can be too high, but 8.7 is not too bad for most fishes and corals. You should try and determine the source of the high pH and neutralize it if possible (unless your particular animals are adapted to higher pH).
It depends what type of fish it is. But in general, I would say yes.
it depends on how soft or hard your fish's skin is. i would say no because some decors are made of clay.
I've never heard a coral reffered to as 'she'. Usually we say 'it' as they are hermaphrodidic. If someone was reffering to corals as 'she' it is just their own personal way, and doesn't reflect the norm.
"Hurt" can be both a noun and a verb. As a noun, it refers to physical or emotional injury. As a verb, it means to cause physical or emotional pain or harm.
no because your fish could die from the high nutrition that your cat needs so i would have to say no
If you hit someone hard enough with it, or in the right place (say... swung at high speed by a 6 year old to your nuts, true story), any lightsaber can hurt you.
To say 'this is gonna hurt' in Japanese you say 'Kore wa kizutsukeru tsumoridesu'.
No, the correct past tense of "hurt" is "hurt." "Hurted" is not a correct form of the past tense.
To say blue fish in Japanese you say ブルーフィッシュ.
To say 'fish shop' in Spanish, you would say 'pescaderia.'
Never hurt your dogs. You can say "no.", But don't hurt them. if you say "NO" IN A LOUD voice then the dog will know that you are angry and he did something wrong
They can do yeh , mine ate his way through over £600 of acans and scollys - never touched an aptasia either :( not easy to catch them either if they do turn out to eat your corals - spent over a week trying to catch him in my 500litre reef tank - finally had to strip the tank down to get him ( not a great experience ) however I have read of other folks having these fish with varying degrees of sucess re aptasia , some say they have never touched thier corals at all - so like many things in this hobby, it's a calculated risk in my opinion
