Help!!!

One of my fish lost part of its Tail in a fight with my betta what should I do!
Ps. I was cleaning the tank and put it in a smaller tank with my betta.

What kind of fish is this?
Lots and lots of clean water! If the fish develops any kind of abnormal growth from this fin (white cotton look etc) let us know.

Harlequin Rasbora. The problem is I am going on vacation tomorrow!!!

For how long?

 

[Shadownova]

Ten days!

No one you can trust to come do a wc? Otherwise do a large wc tonight.

This has happened to my hatchetfish before you could put the fish in a seprate tank until the fin gets better...just suggesting or I just left my fish alone and they stopped fighting and it healed

I just did a wc and that's when my betta attacked! I put them in a little bowl and when I went to put them back in he attacked!
