Ahhh, I started writing a post in fish emergency about one of my Threadfin Rainbowfish not being quite right, and showing symptoms.
 
While I was writing the emergency post, the male threadfin started to swim upside down and sideways etc (what I call a death swim), had to promptly take him out and euthanised him quickly.
 
Pretty annoyed to be honest as do not know why and had no chance to treat him as all this happened in the space of less than 2 hours!
 
The male was showing something suspiciously like dropsy symptoms.
 
Kind of bloated, pectoral fin sort of sticking out.
 
Not swimming a whole lot, sort of swimming gently in soft flow areas, not swimming as normally as other rainbowfish.
 
Gills/breathing a little more than normal
 
Colouration looked ok.
 
Added Indian Almond Leaves 3 days ago, thats the only new recent addition to tank.
 
I did feed a little bloodworms yesterday, realised the bloodworms were a bit on the big side, so stopped immediately and no further bloodworms added, did add a little normal micro pellet feed.
 
Wondering if the bloodworms was a mistake?
Not going to feed these frozen bloodworms again.
Going to throw out the package.  This is usually a very rare treat, once a month treat really.
 
The water parameters are perfectly normal, Ammonia - 0, Nitrite - 0, Nitrate - 5 to 10 ppm, pH 7.6 to 7.8.
Shrimps and snails behaving perfectly normally, if it was a water issue, would have thought they would be affected first really.
 
Going to feed peas tonight in hope this may stop any further events of this illness in any of my other thread fins who by the way are looking and swimming normally.
 
Does anyone have any other ideas what this might have been?
Can dropsy act that fast?
 
And can anyone recommend good frozen foods for Threadfin Rainbowfish? 
Cyclops, daphnia, baby brine shrimps?
 
 
Have noticed one of my thread fins has extremely thin long white poop.
Swimming in soft flow area and staying there.
Not bloated.
Breathing appears ok.
 
*Sighs*
 
What now?
 
Stress? unlikely as all other fish are normal acting and no stress inducing incidents has happened lately.
In fact this is one of my larger males and one of my favourites as it happens!
 
Internal parasite? possible
 
Another effect of bloodworms? possible
 
Going to leave alone for now, will feed peas as already said in earlier post and see if any other developments occurs.
 
Suggestions for other possible treatments would be great. Do bear in mind I have RCS and snails so do not want any treatments that will affect these.
 
sounds like an internal parasite, i would stop feeding for a few days to allow the system to clean through then feed peas. while you wait i would do large water changes... treat the water and allow it to go into the tank through a bubble tube.. to allow the water to now be shocked by cold.. which is what i do.. takes longer but just on the safer side...
 
now you have 16 rainbows in a 24 gallon tank? i would say that it is over crowded IMO
treat for internal bacteria, do water changes, and how is the outside of the fish? fins spit etc etc

Large water changes very day or every other day for example?

Treat the water with what? Needs to be something safe for inverts as well.
 
"allow it to go into tank through a bubble tube" Sorry, not sure what you mean, could you elaborate for me please. Sorry if thats a noob question, just that have never heard of this method before.

I now have 14 Threadfin Rainbowfish actually, my sig is not quite correct anymore and never got round to changing it! Sorry!
 
Outside of the fish is actually fine, no split fins at all, colouration is normal, no pine scales, bloating or anything like that.
 
Thanks for the reply.
 
Anyone?
 
Am planning doing water change this afternoon, advice regarding the above or other comments would be appreciated.
 
The only thing so far that I understand is to do a large water change and no feeding for a couple of days, then feed peas.
 
No idea about treatments, and 'bubble tube' and shock the water to cold.
 
Advice about the above and/or previous posts would be greatly appreciated.
 
you know the tube that is used to hook up to the bubblier, well you have your bucket of water on a higher elevation if possible, and attack the tub so its at the bottom of the bucket, then funneling the water into the tank. instead of dumping the water into the tank it has time to mix with the older water.. 
well if treating for internal parasites you'll have to either add medication each time you do a water change to all the solution to around the fish all the time..
 
just remembered this interesting thing that i did awhile ago, worked. you take any internal parasite solution medication of your choosing and if you have pellets, some sort of fish food to soak in the medication, put the food into it.. allow it to soak and then feed the fish. the fish digests the medication and then it'll allow you to do water changes and shouldn't affect the non-fish in your tank.
what i use if i have internal issues with fish is pimaflex. never tried anything else, and it does the job. never had an issue with snails, or sensitive fish, but don't know about shrimp.
 
Update - 
 
Not fed for 3 days, large water change done.
 
No Pimafix treatment yet as unsure if will affect shrimps and snails.
 
He is swimming about a little more but still nowhere near his usual self. 
 
Did a feed tonight, all other threadfins ate all of the micro pellet food with gusto except this one! Not interested in the food........
 
What to do next?
 
Did you just add the almond leaves or did you microwave them first? They may have something to do with it but only guessing, other than that lots of water changes.

Microwaving almond leaves.......first I've heard of that........gonna do some research into that, thanks for that tip. I just added them straight into my tanks...
 
Lots of water changes, ok, will do another large water change tomorrow. Thanks
 
hopefully your issue will resolve ! I hope your fishy will regain it's vigor!
