Options for which fish to breed in 5.5 gallon?

It's a 5.5, if that makes a difference.
This is more just to see if I can do it, I have a spare 10 I can move adults to after breeding if necessary after spawning.
I have lots of java moss, sußwassertang, anacharis, and a bit of hornwort, and a cycled sponge filter.
I can do just about anything for substrate, including leaf litter.
So I'm looking for interesting little guys, so far my top picks are least killifish and endlers.
I've also been considering sparkling gourami, though I'm not sure how to sex them, would love advice on this.
Invertebrate suggestions are welcome, but not mystery snails, neos, or Caridina
Preferences:
1. Can keep adults with fry and still get a good amount
2. Soft water, my tap is 40 TDS, 1/0 kH, 3 gH. Can buffer, but would prefer not to
3. Can keep with neos (if they need buffered water, and I already know I can't with the least killifish and endlers in the small space)
4. Not super complicated, not likely to kill one another, and if possible, don't need live food for conditoning and the fry only require a few types, like microworms.
5. I'm moving in about a year, so the fry can't take super long to develop/ the parents can take months getting to know one another.
Thanks in advance!

 

You can try scarlet badis. I’ve always wanted to breed them but haven’t had the time to do it.

 

You can't keep any gourami in a 10 liter tank

Even the sparkling ones? It's a 10 gallon, not liter, sorry
Edit: don't want to double post is all
Thanks for the scarlet badis suggestion, I just don't have the room to feed live food 24/7 for adults and fry... But thank you, they really are gorgeous and I was considering them for a long time

 

Are there any egg scatterers that would work?

 

They would be fine in a 10 gallon for breeding only. Hmm have you tried dwarf gourami's? That would be a fun experiment as long as you have time on your hands.

 

Okay thank you! And I hadn't considered dwarg gouramis, mainly because I don't have a suitable tank to house them afterwards, or I'm not sure I'd be able to find new homes fast enough, and I've heard the females are pretty rare. Definitely something for me to consider in the future...

 

Hmm do you wanna try rainbows?

 

Sorry, do you mind helping me out with the scientific name and all? Haha, I'm still relatively new to the hobby, and the only rainbowfish I know is the boesmani, and I know those guys don't work lol. I would love to have a tank of them one day though

 

Sure haha. Neon rainbow(Melanotaenia praecox), threadfine rainbow(Iriatherina werneri), red rainbow fish( Glossolepis incisus) , glossolepis(glossolepis)

 

Sparkling gourami can be kept in a 10 gallon size tank indefinitely. They're small, somewhat shy, like lots of plants, and you can house several of them together unlike many other gourami. From what I have understood the best way to sex sparkling gourami is to shine a light behind them so you can see through their body and locate ovaries or the absence of ovaries. They don't build bubble nests at the surface but build them under leaves. I have had no success breeding mine so far but I also I haven't made any spectacular attempts to breed them... yet.

Oh very interesting! I especially like the look of the threadfin rainbow, I'll definitely do more looking into these guys.

Very good to know, thank you!

 

Haha have fun

 

I have no experience with these but check out Gertrude blue eye spotted rainbowfish aka

 

Oh I really like the look of those too! Thanks for the suggestion!

 

Cherry barbs are easy to do in a 5

I don't have a 20 to put the adults in, but thanks for the idea! I almost got some of those guys a while back... They're pretty

 

You said you had a ten. I’ve kept a group of 6 in a 10 for a little over 9 months now

 

Although that’s a debated subject on whether on not that’s ok

 

Yeah, I've seen it debated a lot, and surprisingly they're uncommon in my area, I've seen five arowana and countless rope fish for sale, not to mention actual sharks and massive flowerhorns, but not a single cherry barb...
If I do see them, I'll definitely keep that in mind

 

If your going to I would recommend getting 3 males 3 females and putting 1 female in the 5.5 gallon and feed live or frozen food for 3 days then add the male on night 4 and remove in the morning after a hour of lights on then add java moss to catch food for the fry
