More background/history is needed here. A short video would also help. Here is a link to how to provide that information:

From what I can see, both fish are producing excess mucus. That can be due to Brooklynella, late stage ich or water quality issues.

Hi Jay, sorry for my lack of information i was a bit distressed this morning when i made the post.
So for information...
History
I had 4 fish in the tank for 2 weeks, one of them coming from an older aquarium. They where all doing great showing no signs of sickness or anything. I then added a small hippo tang, which hid for a couple of days but eventually came out and started eating well. After a week the hippo got a few small white dots which i would say looked like ich, this persisted for around 4-5 days, but without bothering the hippo, it was still swimming around and eating. Then its situation got worse it got completely covered in white spots and started looking dusty, also getting cloudy eyes, it stopped eating and hid away for about two days. On the third day it was out and about swimming and eating again looking a lot better, the dots where dissapearing and the dustiness had gone away. Then a couple of days later i started noticing white dots on the fins of my angel and blenny, these didnt get worse and dissapeared again quite quickly, they were also eating fine and swimming around happily. Then about two days ago i noticed one of my clown fish had lost its appetite and was looking a little dusty, and now today my hippo is back with dots, looking dusty, aswell as my midas blenny is looking dusty. And at this point all of the fish has also lost most of their appetite, but are still swimming around, without laboured breathing.

So far i have not medicated at all
I hope this is more usefull than my initial post, im probably just looking for some sort of idea of what could be wrong with them. Im not sure i will be able to medicate since fish medication is illegal to sell in my country, and its pretty hard to get a hold off trough import sadly..
