There's a combination of words I never thought I'd run across.

I won't judge anyone who disagrees, but I would go with the trio. As mentioned above, most gouramis (with dwarf gouramis being the notable exception) are social and do better in groups. In the situation you described I don't think adding a trio of honey gouramis and eight or so neon tetras would be a problem.

Hello and welcome to the forum. To start with, while they aren't shoaling fish, pearl gouramis are social, and often do better in groups than solo. Because of that I'd encourage you to get several instead of just one. I'd say a minimum of three, with one male and two females, but increasing it to five (still with females outnumbering males) would be better.

To quote the article: "An aquarium full of fish could generate as much CO2 as running a motorbike." It could generate a great deal less also.

When shipping shrimp, or fish in bags with corners, I typically invert one bag in the other. That eliminates the corners. This is with non-breathable bags, of course.

Possibly, if you have a water softener, but otherwise it's all the same water. I've stuck a hose through an open window to fill a tank a number of times, and water from the hose is all my outside tubs get (except for when it rains, of course).

It may not be "authentic," but I like putting some fresh spinach on them instead of lettuce.

I've had good luck with these: https://www.amazon.com/gp/product/B09M6X73DR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. They're 10" x 20", with rounded corners. I use them to ship guppies; usually splitting 50 into three bags. I add two cups of fresh water, two cups of tank water, and then as much air as I can get into the bag (roughly 1/3 water and 2/3 air). I double bag and pack them with the bags upright in an insulated box. They typically arrive two or three days after shipping with no deaths.

About 25 years ago when I was working in North Dakota a local took me to a Mexican restaurant in Bismarck. I guess for people who never had the real thing it was okay, but I thought it had about as much flavor as plain boiled potatoes.

Not me. I have arrived there.

I stop at a local convenience store for breakfast every morning. They stay so busy that they have at least four, and sometimes five, people making and serving food. Everything is homemade, including the tortillas. I think my favorite is half beef fajita and half huevos y papas (eggs with potatoes), with refried beans and their tomatillo based salsa.

Maybe. I have a tank on my desk at work, stocked with guppies, shrimp, snails, and a dwarf Mexican crayfish, that doesn't have any mechanical filtration or water movement. The only appliance it has is a light. It never has a protein layer.

No, I don't believe that is too many fish. In fact you could probably add a few more of the diamond tetras. I wouldn't add them all at once, of course.

As you proceed with your MTS addiction (Multiple Tank Syndrome) I'd like to mention that the smart devices aren't strictly necessary, and a sturdy piece of used furniture from Goodwill will often make a perfectly serviceable stand.

I wouldn't worry about 10 ppm. The shrimp in my tanks don't show any problems with it at 40 ppm.

Just a heads-up, the subwassertang may dwindle down to where you think it's all dead, but then come back strong (at least that's what happened when I first got it, and I also have hard water).

There may be some air trapped in the top of the intake tube. If yes it will probably get better soon.

So you're a second hand vegetarian? (Cows eat grass and you eat cows.)

For the record, duck weed is not pushing meat off my plate.

I couldn't find it the last time I looked, but I'm sure I once saw a youtube video where @Cory used a shop vac to suck it up.

I have some in my 65 gallon tank that seem to be blooming every time I look at them, and they definitely aren't dying.

I didn't read through all the replies, though I did skim over them. In any case, I doubt very much that nitrates killed the fish, unless it was well over 80 ppm.

Shrimp did fine with endlers for me. Maybe you don't have enough places for the babies to hide until they get large enough for the endlers to leave alone? Or maybe your endlers just are different from mine.

Those numbers don't look any higher than mine, and probably lower (I know my pH is higher). Red, yellow, and blue neocaridinas do just fine for me, though after several generations they may not be as large as they would in water with somewhat lower values.
