1 Fish Left

HI Guys.
I had a school of 5 harlequin rasboras.
All of them died, due another school of fish sickness or something, except for 1 harlequin.
I didnt think he was going to make it, but its about a week, and hes still strong and alive.
I don't have a quarantine fish tank as back up, as I did not have a need for one till recently.
I want to get him some buddies, but like I said, I don't have a quarantine tank & I don't want to leave him alone for long (having to cycle one & then keep the new fish quarantined feels like a long time)
There are other fish with him such as a school of glass catfish & zebra danios.

The point of my thread is because I don't want to get rid of him and was wondering what I could do in order to get him buddies.
Should I start a tank for quarantine, should I leave it alone? Any advice is greatly accepted.
Again, I don't want to lose him or rehome him, or at least I would not like to.

 

He can be alone IMO. Whenever my schools die off I keep the stragglers. There's always a chance that rehoming him could lead to an even worse situation.

 

Rasboras do like to have schooling friends. Watch the Zebra Danio's because I have heard they will pick on smaller fish at times. They could put a lot of stress on your Rasbora. If it were me I would just add 4 or 5 more Rasboras to the tank. But I'm no expert, that's for sure.

 

It's always pretty important to have a QT tank set up! You'll pretty much never stop using it once you have it set up! I don't know too much about your fish in particular, but I'd suggest setting up a QT tank regardless.

 

to start up a qt tank I usually fill it with tank water and steal a piece of filter media out of my tank filter and its up and running in about 1/2 an hour.

That is exactly what I told my mother! That I did not want to rehome them because they can stress them out even more.

I have about 6 zebras and they chase each other around! I've kept an eye on him when I feed him & hes fine, I make sure he eats and rests well.

I know, I just stopped adding fish once I had set it up. I am considering getting one tomorrow.

I have an extra piece of media stored in my original tank. Its been there for like 6 months.
Do you think adding that & some tank water will help get it cycled fast ?
What do u do when there are no fish in the tank to keep the bacteria alive?

 

I usually just dump it out and store it dry under the bathroom sink or in the garage. With the used filter media it will basically be already cycled as it has all the bacteria needed for a cycle. You can use new water if you would like instead of old tank water since very little bacteria is in the water. I usually use old tank water since then I don't have to worry about temperature so its ready to go as soon as its set up.

Thank you so much, I am going to try this tomorrow!!

 

A sterilite tub is useful, the 5 gallon tub is perfect for a temporary QT because it is easy to setup and take down, you don't need a light, and it handles a heater being suction cupped to the side just fine with no melting issues and the tubs are food safe (so they are fish safe, I briefly kept a spawn of plecos in one because dad kicked them out of his cave so I took over).
