Responding to issues in your last three posts.

Did you quarantine the new fish? What are your water parameters, meaning GH and pH? Endlers need moderately hard water, neons do not.

To the airstone, never mind the plants, use the airstone if fish are gasping and this relieves them.

Tests. When you do any test, please always post the numbers. What you consider "good" may not be what we consider good, and with the numbers one of us might spot something. Ammonia, nitrite and nitrate are important here. And pH.

The UV Sterilizer should kill any bacteria in the water passing throough it, and the unicellular algae. Bacteria on the surfaces (substrate, filter, etc) should not be affected. So what this means is that the nitrifying cycle should not be harmed. Fish gasping at the surface can be due to many things: high ammonia, high nitrite, high nitrate, high CO2, sudden change in pH, warm water, parasites... .

Reading back through this thread, I am fairly certain the increased ighting caused this, plus organics/nutrients. What are your water changes now, in volume and frequency?

Byron thank you very much!

I'm using the API test kits.
I did not quarantine the fish.

Here are the numbers:
Tank temp is running between 78-80 degrees, the temp in the condo hits 80 during the day here lately as well...
Ammonia 0ppm
Nitrite 0ppm
ph 7.6 + it is a darker blue than the card. But it has always been that for the last couple years and a couple of the shops I buy from said that's normal here in CO. I did add a couple natural wood pieces last week and was told that may help with the ph.
I don't currently have a nitrate tester though I'll pick one up today.

My last 50% water change was last weekend and all tests where the same as the test's done this morning. I did add about a gallon of water last night bringing the water level up along with 1oz of Flourish plant supplement by Seachem. I use tap water that's run through a double filter system that I have had it tested and they said I was good to go, so I've not been using any conditioners during water changes. Again this has been my practice for the last couple years with no problems. I will admit that my filters are due to be changed at this time.
I do have some Prime here and could add it to my water but I'll wait till I hear back about what you think.

Thank you.

follow up

so it's afternoon and i pulled the air stone a few hours ago and all my critters seem to be doing great. could it have been that I added a plant fertilizer just before lights out (no photosynthesis) could have caused the issue???

A few things here.

First, I would use a water conditioner with water changes just in case. You are using tap water which will have chlorine and possibly chloramine; while a water purifier may say it removes these, I would not want to chance it. And while I am not saying this is the issue, I will say that if there is chlorine in the water, you would expect to see fish at the surface as you describe. This is just one cause for this.

You may not need Prime regularly, depending what is in your tap water. The other issue is the filter/purifier. What exactly does this do? Is it a softener too?

The Flourish should not cause this, but I would add it in the early morning. Plants need nutrients during daylight when they photosynthesize. I always add any plant fertilizers just before th etank lights come on, or just after if I forget. Again, not likely the issue, but...

It wouldn't hurt to leave the airstone in tonight; something seems to have happened over night, and we don't know exactly what, but this can't hurt for a night. The see what transpires tomorrow.

On the pH and fish, 7.8 is good for Endlers. The wood is not likely to change this, or very little. But what is your tap water GH and KH? Check the municipal water supply website for this, it is important.

My filter system is the Whirlpool WHED20 designed for Municipal and Private Well Water Supplies Reduces Sediment, Chlorine Taste & Odor, Cysts, Lead, MTBE and Volatile Organic Contaminants (VOCs).
When I pulled up the water municipality it's graph show'ed average KH as 119 and the other "Total Dissolved Solids" which I'm assuming is GH at an average of 266.

GH is part of TDS (total dissolved solids). If you can provide me a link to the web page I can take a look, I might be able to narrow this down.

I checked into the water purifier online as best I could; all I can see is the claim that is "reduces chlorine taste and odour." This may not be removing chlorine. When you have performed water changes previously, have the fish ever reacted anything like they did this time?
