I don't know the answer but, I have the same fear. I have full on panic attacks when I start to get close to an aquarium. I do not have a fear of water, or fish in open water. I can go fishing and not be afraid. It is strictly fish in a tank!
There is not a name for this phobia but here are a couple that could explain why you are afraid of fish in a tank.
Claustrophobia is a fear of confined spaces.
Hyelophobia (or Hyalophobia), Nelophobia is a fear of glass.
Aquaphobia or Hydrophobia is the fear of water.
a small fish tank.
If it is a bowl shape, it's called a fish bowl. Otherwise it's still a tank.

fake plants my fish loves them
You simply call it whatever you wish to call it. I have a fish tank called Claud.
the stuff that builds up on your fish tank is called ''algee''

usually if you have a tank with a bigger predator fish and in your tank you had fish smaller than it the predator fish would follow it around sneaking up behind it then lunging for it
the best tank cleaners are bristlenose plecs. they aren't violent at all, in fact there the least violent suckermouths. get them as young as possible. there not fighters though, so violent fish are a definite no. try to get them from auctions
It's kind of inappropriate
There are a variety of fish that can keep a tank clean. The type of fish will depend on the type of aquarium setup. In a freshwater tank, different types of plecostomus are most common.
