Would these fish overload my tank?
I have a 10gal tropical tank with a Tetra Whisper 10-30gal filter. It's oddly stocked and I want to add enough fish to have the min school size without overloading my tank. Right now I have...
1 Male Veiltail Betta (he is actually VERY sweet! :-D)
1 Mystory Snail
8 Ghost Shrimp
3 Neon Tetras (shopkeeper misinformed me on min school size when I bought them)
1 False Julii Cory Cat (he was the last one)
1 Black Tetra (was gift for friend, but found out she is not good at taking care of her fish and poor Lolo would have most likely had a short and misrable life with her)
I test my water and do pwc REIGIOUSLY! All my current fish are happy and healty. I also have 1 Anubias, 2 aponogeton, and a marimo ball
I would like to add...
2-3 more False Juliis
2 more Neon Tetras
1-3 more plants

This is rather a difficult situation. Obviously the two tetra species and the cory will be much happier (= healthier) with a group, but to do this adequately will really push the limits of a 10g. There is also the Betta to consider.
My first choice would be to add 2-3 more corys. The C. trilineatus (which is the actual species that stores usually call Julii) is a relatively small cory species, so this will be fine.
The tetra are an issue; without more in their group, both neons and black neons have been known to turn nippy, and your Betta will likely be the target. I don't know how long these fish have been together, but I wold keep a very close eye on this. Even if the tetra "think" of nipping, it will stress the Betta (allomones in the water).
In an ideal situation, both tetra should be increased to no less than 6 each, preferably more. But this is also likely to bring out increased aggression due to the cramped quarters.
A catch 22. Any chance of a larger tank, a 20g long would work well, though the Betta is still a concern.
Is there any way to return the tetras? I think all fish involved would be a lot happier.
No. And no way to rehome them either as the only other fishkeeper I know around here has a sub-tropical. Again, I never meant to keep the Black Tetra, but if I gave it to the woman who it was meant for, she would kill it. She really has no concept of how to truely care for her fish and does crazy stuff like keep 4 goldfish and 6 ghost shrimp in a 1gal hex tank! I'm hoping to get lucky and re-home it somehow, but Lolo is stuck with me ;)
The way I have the bioload figured out according to my research...
The Ghost Shrimp really have no bioload to speak of
The mystory snail is worth a gallon
The Betta is worth about 2.5gal-3gal
Black Tetra would be 1 gal
Neon would be about 0.5gal each
Juliis have a bioload of 1-2 gal each
My current bioload would be about 7-8.5gal.
With 2 more Juliis? about 10gal
I might be able to swing the 2 more neons OR 1 more Julli if I add a few plants. I worry about adding 3 more Juliis and 2 neons. If I could give away the Black Tetra, it would free up a good bit of space. I've grown attached to him/her (I think it's a her, but hard to tell without others around), so I just don't want to give her to the 1st person with a tank. If I wanted to do that, I would have given her to my friend!
The mix has been in the tank since Thanksgiving. The only time Gus (Betta) and Lolo (Black Tetra) don't get along is on bloodworm day. It's because Lolo LOVES bloodworms and unlike most days when she lets Gus eat his floating stuff and then she eats when I release the midwater food, she zips and zags trying to beat him to every bite! Not that Gus really raises a fus (he actually prefers his pellets over bloodworms if you can believe that!), but he gives her a good staredown and puffs at her to show that he does not approve. It's more cute than agressive, treating her like the anoying little sis than a rival. I've really never seen a Betta that acts less like a Betta than him! I worry about when she gets older though which is why I really want to find her another home.
My dad is not exactly understanding saying I should just throw her in the creek! And she would survive how many seconds? *eye roll*
I had for some reason thought blackneon earlier...what exactly is the "black tetra?"
This is probably a case where you simply stay with what you have, with one exception. Definitely absolutely get 3 more corys. This fish is just too social to be alone. The tetra, well, let's hope.
I don't fully fathom the fish/gallon thing, although I think I know the background. But I have never bothered with that sort of stuff, just like the inch of fish per gallon guide. There are just too many variables for any of these things to really help. Fish need numbers, space to be themselves, a proper environment and water parameters, and no stressing tankmates. Water quality can be controlled with water changes if needed.
I didn't do the whole "inch per gallon" thing as I don't trust it either, but I did do research on the biological output of the fish I have. I really was surprised at the volume of output a little snail has! And people say they have no bioload *rolls eyes*
Bettas may be able to live in small spaces, but they put out a good bit of amonia for their size. Juliis don't put out a crazy amount. Most people don't count the neons, but their output adds up!
The black tetra is just that. A black tetra. It's what PetSmart had it labeled as. It was on of the black friday fish if that helps. The woman who sold her to me as a fish that was "labeled as schooling, but would do just fine alone" (like with no other fish period which is why I thought it would be good for my friend) was also the same one who told me that "The minimum Neon Tetra school size is 3" and "Neons die very easily and need dirty water to survive so don't be surprised if they're d by tomorrow."

I would love to use the profiles, but as you can see, I'm posting via a mobile device and the profiles don't work on mobile devices. I did a google search on "Black Tetra" and found my fish. It was refered to as a Black Tetra, so I'm a little confused. I do know that it's not a phantom (the markings aren't right). I also know that its max size is 2.5in, min tank is 5gal, it's and omnivor, a midwater swimmer, and schooling fish. She is silver with mid-black stripes and an opaque tailfin.

I just did a Google search for "Black Tetra" and every site that came up was on the Black Widow Tetra, aka Black Skirt Tetra, so presumably that is what we're talking about. Photo below.
This fellow can be nippy, more than most tetra, and alone may be a real problem, so keep an eye on it. They get largish, 2.25 inches with some saying 3 inches is possible. I personally would rehome this fellow if at all possible.
If it is the black widow tetra then I would definitely recommend finding a new home. I have one and he is constantly harassing my four rummy nose tetra. It actually looks like territorial behaviour. I also have a 10g tank and currently looking into getting a bigger tank just for him/her and a few friends of the same genre.
