What to do now since tank crash.

I had a crash that literally happened over night. The salinity checked out fine, so did everything else except ammonia was 0.50PPM.

The fish all had skin that looked like it was flaking off, a little bit of redness, but a little brown. Some just had their skin flaking off with no abnormal color.

I was advised this may have been a Fungal infection, but it literally attacked over night, maybe the signs were late?

What should I do to make sure my next inhabitants do not get this transferred?

The only thing currently alive in there now is a Snowflake Eel and was not affected by it.

What I'm thinking now is a

V. Lionfish Saltwater Aquarium Fish for Marine Aquariums: Volitan Lionfish, Colored
FoxFace Lo (Maybe magnificent) Saltwater Aquarium Fish for Marine Aquariums: Foxface Lo
Scorpion fish Saltwater Aquarium Fish for Marine Aquariums: Orangebanded Stingfish

All into a 75 gallon -- 105 gallon total aquarium.

Or a Dwarf Angel tank -- Or a butterfly fish tank!! I'm not sure what to do and will be patient with my choice.

Insight is welcome

 

Dwarf angels can be very aggressive with other Dwarf angels, I would not mix them. They are very difficult to catch.

The Volitan gets too large for a 75 gallon.

Fox Face would work.

If you do Butterflies make sure to get the hardy types, and a specimen that is fat and healthy.

Perhaps look into wrasses.

Regardless I would let the tank sit for awhile to make sure there is not active disease. Also looking into your filtration and feeding regime, a fully cycled tank should not show any detectable ammonia.

Judging by the physical appearance of the Trigger fish, you might want to consider water quality over pathogen.

 

dont add anything for at least 6 weeks. Did you recently add anything new to your tank? How long has your tank been up? How fast had the fish been added? How many fish did you loose?

Look up velvet and see if the fish looked like that. Velvet can wipe out a tank almost overnight as by the time you see the first sign, it is often too late

Regardless, anything new you add to the tank will be exposed to whatever wiped out your tank. I personally would be ultra safe and not add anything for 3 months, however you need to wait at least 6 weeks.

 

I added dry Florida rock I got a few months ago. It has been up for a few months, 6 fish. Each were added a week apart complimented with some bacteria in a bottle. I will wait 6 weeks, probably more to play it safe. I actually just remembered I've always liked the octopus tank I saw. Hmm..

 

Update: One fish still alive!! One was hiding and came out randomly with no signs of anything... Hmm?? Fed it and it ate but went Back into hiding
