? Yellow Tail Sword ? #1
I done things a little backwards today and brought three fish without researching them first.

The man at the fish store said the fish would be ok and had them labelled as 'Yellow Tail Sword', I have looked everywhere online and cannot find anything relating to that name.

The gentleman in the store said they are rare, which kind of convinced me to buy them without researching them. (Bad I know!)

I have a freshwater tropical tank, I have attached three photo's below. They initially had white tails, but these have turned Yellow as they have settled in.

It won't let me upload the photo's, so here is a link:
1.) https://www.dropbox.com/s/w1422hnmwu03 ... 04-04%2022.06.40.jpg?dl=0
2.) https://www.dropbox.com/s/iwqhoj9lfgaj ... 04-04%2022.06.44.jpg?dl=0
3.) https://www.dropbox.com/s/wn65zcz82yon ... 04-04%2022.06.47.jpg?dl=0

I was hoping someone could help me identify these new fish.

Re: ? Yellow Tail Sword ? #2
These are not Swords, they are Yellow Fin Rasboras (Rasbora dusonensis). They aren't especially rare and are listed as least threatened on the IUCN list, but aren't imported as often as other Rasboras.

These can grow to 12cm long and need at least a 4ft long tank and to be kept as a shoal of at least 6 in soft acidic water. They can jump, so a tight lid is needed.

Re: ? Yellow Tail Sword ? #3
Thank you very much for your reply, that is certainly my new fish!

My PH level is a little high at the moment, it is normally stable at around 7. According to http://www.seriouslyfish.com/species/rasbora-dusonensis/ up to 7.5 is ok, but I will try and bring my PH down a little as per your suggestion.

I do have two slight openings on my tank where the cables enter my tank so I will look at anti-jumping tactics first thing tomorrow (Almost 1am here).

They sound like graceful fish that will settle into my new aquarium well, I will look at purchasing three more once I have sorted the problems above out.

I wonder sometimes how you guys can find and categorize these fish so fast!

But thank you very much for your help.
