Help- Loosing All Fish Fast

I was a fool and did not properly cycle a brand new tank that I placed some of my day one fish into. I was upgrading them from a 28 to a 40 gallon. New tank syndrome and ick started to infect the tank. Not wanting to loose my Gourami, one of the last ones left in that tank to survive and not have spots, I scooped him and put him into my only other tank- the 55 gallon.
Next day my two silver dollars in the 55 had full blown ick. Next day they both die. Then one of my original fish I ever bought that I raised from a little cichlid dies. I feel like I should just stop keeping fish. This is devastating to me. I made such a colossal mistake and then another huge mistake right after it. And now one my last remaining fish in either tank, the Convict I've had almost the longest of them all, is dying. I've been dosing both tanks daily with Marineland Ick Remedy and doing a 25% water change every 24 hours per the bottles instructions. Now my remaining Convict has lost the little white spots but it looks like white mold covering its body and eye. Could this be a secondary fungal infection?

 

Yes, I assume a fungal/bacterial issue. I would recommend Kanaplex. I’m sorry this happened.

 

If it looks like wet cotton it may be a fungus. I had a parasite and ich problem simultaneously and I was reccomended to use Tetra Lifeguard. It basically treats everything (Parasite, Fungus, ich, bacteria) and it worked well for me. Has your ammonia spiked since starting treatment?

 

Would lifeguard or kanaplex be dangerous to a blue crayfish? I have one in the 55 gallon. Tested the ammonia, levels seem to be normal.

 

Hmm. Do you have another tank he could live in, while you dose meds for the next week? There might be traces of copper in the medications, which might irritate, or even kill your crayfish.

 

No my only other tank is being medicated but I do plan on buying a ten gallon so that I'll have a qt tank/hospital tank in the future. But if I bought one now I'd have to let it do its cycle for 4-6 weeks before using it right?

I'm also weary about dosing the 55 with anything that could hurt the crayfish even if the crayfish isn't in the tank at the time in case trace amounts are left behind even after water changes. I do want to try KanaPlex though. I can't seem to confirm if there is copper in it or not so I sent a message to their manufacturer through their website.
Maybe I can supplement the Ick Remedy with KanaPlex if it turns out to be copper free.

I checked the Convict today, he is still posted in the plant but the white stuff has largely gone away (although it is definitely still there).
I was thinking about how ick triggers the fish's immune system to enclose it in those white dots and wondered if maybe I was looking at burst cysts? At the same time my Gourami has an eye that is completely clouded (it was swollen and three times the normal size before I put him in the 55, and now all the swelling has gone down and it's just clouded) so maybe it is fungal. And the behavior of the Cichlid- I'm wondering if that is a sign of him dying or is that his way of hiding because he knows he is to weak should he have to defend himself?
I'm praying he pulls through, he has had no appetite the last couple of days.

 

Kind of scary that Seachem's reply is from a guy with a Gorilla icon (fish, gorillas- I don't see the connection) that can't spell medication. Anyway it looks like there's no copper, that's good to see I'll have to try it out. Thank you for the suggestion.
