Help identify the fish.

Gentlemen mariners, I was recently in Egypt and took many photos. In my opinion, this creature could be tried in an aquarium. I wanted to know what it is called and how large it grows. In the second photo, it’s probably a worm. (Is it not worth introducing it?). In the fourth photo, I saw individual specimens up to 30 cm, but mostly up to 10 cm.

In the fourth photo, there is a fish that only eats acropora. It is sitting next to them.

Why exactly such animals? There are many other very interesting ones.

Because they are very small in size. (That's probably why they are not mentioned in the guide to the Red Sea).

I would accommodate such people, but the sizes do not allow.

In the second photo, there is a very aggressive creature. But the dog is beautiful. In the 10th of March, there will be a delivery, come by and take a look, I think you'll find the right fish for your jar. And the sizes... that's always a problem. It used to be in increments of 30-150-300-500 liters. Now I want about 3 tons. Just need to set up the bed in the aquarium.
