My fish are dead

In the tank
I blew them out with a turkey baster
Waited for the filter to get the algae out
I cleaned the filter

In my opinion that eliminates The rock cleaning as a problem.
Honestly I can’t remember if you said or answered this but did you test your water you made up for the water change? Did the PH match? are you using RO water?

 

[40g Nano]

I used RO water
I did not check parameters of it

I fed my tang one 3 inch strip of sea veggies a day and he was eating it all

That may point more towards internal parasites then. However, eating was a good sign. It truly seems to be a mysterious death.

*I just noticed that I am reading the posts in the voice of the unsolved mysteries guy. ;Joyful

All at the same night though?

 

[MichaelReefer]

Having a tang in a small tank like that...wouldn't be surprised if it didn't get stressed out and get something...

 

[40g Nano]

How would the clowns get it though?

Looking at your first pic, I don't see any powerheads. This implies that you rely on your circulation pump for all water movement and oxygenation. Circulation pumps in these small tanks get clogged from buildup and need cleaning every few months. If your pump was operating at a reduced rate due to clogging, then your tank's oxygen level would be getting lower and lower each week. The fish may have become oxygen-starved and weakened just by the passing of time and not by any lack of feeding.

In my 10 gal QT AIO (All-In-One), I always run an air-stone because the circulation pump is very weak.

My first death was my clowns when I first started. I had no clue why the first one died. It happened over night. The other one had obvious signs of Brook and died a few hours later, which is the only way I could deduce what may have happened to the first.

I think everyone is just sharing their own personal experiences for why they think they have had mysterious deaths in the past. It may be impossible for you to ever truly know what happened, but at least you may have some ideas.

Also just an observation, but you are not providing a lot of info, so it's not easy to help and you will get a lot of passive aggressive comments. For example - you were asked for the temp (prolonged high temp could kill fish), and you responded with "I don't run a heater it's hot in Florida".

I agree with this. Just because the OP isn't running a heater doesn't mean the water temp isn't sitting at 95 degrees and they're being cooked. It's amazing how quickly tank water will equalize to air temperature. I had a 15g FW tank with no heater jump almost 8 degrees on a really warm day in early spring. Totally caught me off guard. I had to break out the fan. I could have easily lost all of my fish.

Should I get a Powerhead now



And how long do you think I should wait before getting more livestock

Yes

3 months

Yes...you should of at least had one in there from the beginning...even a cheap one.


Like most said, if the fear is disease, at least 3 months.

 

[40g Nano]

What about corals

 

[40g Nano]

Is there any supplements/ medicine I could put in to kill any parasite

 

[MichaelReefer]

Honestly, if you want to get back into it quicker you'd probably be better to just wipe the tank and start all over. New sand, new media, bleach everything. You can probably get back up and going in 6-8 weeks.

 

[Bleigh]

Just feed occasionally for the corals. I use amino acids also, but its not necessary. Still keep an eye on nitrates and phosphates and do water changes as needed. If you do 3 months without fish, that should starve out all the parasites, so you won't have to worry about medications.

 

[40g Nano]

I don’t think I want to do that

I’ll just continue setting up my 40

I'll second (third? fourth??) lack of oxygen. Ammonia probably wouldn't spike that quickly, and 14g Nano was testing 0 ammonia anyway. Diseases take longer to kill also, and he/she would've seen some kind of sign that they were unwell.
