Threadfin Rainbow

[vanalisa]

Have you kept them or know about them?
I really want to get some; my LFS has had them for a month now and the are looking good...

 

[Sgooosh]

if they had it for a month, there are no diseases, make sure your water conditions match. i might be getting dwarf neon rainbows..
i was told all raimbows like to be in hard water.

Yes, they are nice fish especially when the males open up their fins competing against one another just like the Bettas fish.

They are from the soft to slightly hard water.

They have very small mouth and need fine food and they are very peaceful.

If I am able to arrange it, I will be keeping them with Peacock Gudgeons and Blue-eyed Forktails. I am in a frenzy over it! My water is fine; my Blue-eyes are breeding.
I haven't the time or space to comfortably accommodate the Threadfins.
I was also considering the Dwarf neons as my LFS also has those, but I think I will be limited by the sheer mass of them compared to the Threadfin.
I hope they last a couple weeks or I will have to pass this time around.
They are just so darn good looking!
I simply CANNOT set up a QT tub, nope, can't do it, no way......

Thanks for the link!
I want them even more now as they fit the parameters and temperament of the fish I plan to house them with. They are so graceful and delicate and mild.


Oh my!!!
What to do what to do what to do?
I'm moving in a month or so, haven't the large tank yet, and have a WCMM project, Peacock Gudgeons in QT fresh from the LFS, and fry I need to grow out.
Yikes.

Oops...Peacock Gudgeons can be a threat to them with their big mouth.

I kept Peacock Gudgeons before, and they can do sneak attack on other fish.
In the end, I had to return the Peacock Gudgeons to a fish store.

Threadfin Rainbows have big fins which can be vulnerable to the Peacock Gudgeons...
So, it's risky to keep them together.
Anyway, others may have different experience with Peacock Gudgeons.

Peacock gudgeons aren't a problem, but other bigger gudgeons will eat small rainbowfish.

Get the threadfins but quarantine them so you don't introduce anything into the furcatus tank.

Iriatherina produce much smaller eggs than P. furcatus and the fry are really small and need green water and infusoria for the first 2-3 weeks.

Get a group of 10+ fish and try to have similar numbers of males and females. Males have the long fins and colour, females have short fins and not colour in the fins. Young males look like females until they mature.

Hmnnn.
Well maybe with my upcoming WCMM tank...(I have a dozen of those eager to get into a bigger tank). That red combo would be sweet against nice green plants. But I think the threadfins like warmer water?

My gudgeons are to be added to my Blue-eyed Forktail tank. The gudgeons seem very peaceful and I have 7 so they should feel safe
I'll be understocking so maybe that would help...
We'll see how it goes. As mentioned, plenty on my plate!

Well it was to be my forktails, gudgeons, and pondering the threadfin to complete my tank
The research I've done corresponds to the info you provided, and all have been noted to have peaceable dispositions.

I have:

7 gudgeons, 3m/4f

6 adult Blue-eyed Forktails 2m/48f
+ 7 youngsters (as seen in RCS tank), at least 3 sexed as male so far---so at least a dozen

I was pondering at least 3m/5f of the threadfin.

That's 28 fish and am going for no smaller than a 40g.
Plenty of plants.

That's the plan so far !!!

Threadfin rainbows need warm water between 18-30C

If you have peacock gudgeons in with rainbows, the gudgeons will eat any rainbowfish eggs they find, so if you want to breed the rainbows, you will have to move them into a separate tank for a couple of weeks. Then move them back into the big display tank. You should be able to rear up the babies in the breeding tank.
