Need Help The Rest Of My Fish Are Dying

[Daynarita]

I have been getting over ich. Now something is wrong with the reminding fishes eyes, they have this thick white crap over their eyes all of them now, it makes it look like their eyes are larger or popped out.

Everyone's eating, did a water change last night. Using super ich cure and tc tetracycline. I have melafix too. Following the instructions to the letter. My blue female Betta isn't really blue anymore... Like silver or gray. The water is the right temp, all the other things test out fine apart from the ammonia which is a just a bit high, I don't have a carbon filter in. The bettas fins look like she's being attack but I'm wondering if its fin rot.

Then I have three other mollies that's all that's left. No more ich spots tho...

Having any ammonia in a tank is enough to cause serious problems! Try using some 'stress zyme' to reduce shock from ammonia

get a carbon filter and do a 50% water change, you can also try putting a little aquarium salt in. You may have too many meds in at once. How many gallons is your tank? What are your water stats?

Poor water quality issue. Ick and what looks like to you as fin rot, are caused by ammonia more than likely initially, or your bacteria is dying because of the medication used.
I've heard Melafix can kill labyrinth fish like Betta.
If that fin rot is really fin rot and not ammonia burn, then it is contagious and all your fish should have it , or will get it in no time. Otherwise, it could be just the ammonia taking it's toll.

I would suggest checking the ammonia reading exactly. What is your test showing? Do a large water change, even 2 if needed to bring it to as close as possible to 0 as you can. Check in 2 hours time, if ammonia is rising, you are back in a cycle and medication will complicate it further.

Pop-eye, or at least based on your info, can be caused by bad quality water as well, or some bacterial infection.
To prevent the fish from losing their eyes, get Epsom Salt if you can(this is not normal salt, it is Magnesium Sulfate) and dose it at 1tbsp per 5 gallon for a few days. If it is the water quality issue, this and water changes could deal with it.
