Harlequin Rasboara dying one by one...

Yeah they just got back to me and told me to take my receipt, take a few pictures and a water sample and they will "sort it" for me. I am not sure what tests they use but if its the API kit then they are only gonna get the same reading as I am. Cool if they can offer replacement fish but not going to be much use if they are just going to die again.

They probably use something similar to test. As you say, it should be the same which means you'll get a few more fish. If you've ruled out your set up as the problem then getting different fish might make a difference.
 
One last question for now, I have about 10 plants coming tomorrow morning in the post, do you think I should add them to the tank or wait until this issue is resolved? I don't have space/money to have a secondary/QT tank so not quite sure what to do with them?

Do you have a bucket you can keep them soaking in?

Just one other question which may have been asked before but can't see it. Where did you get the sand from?
 
If your test kit was new when you set the tank up it should be fine. And the fact it has given different readings for nitrate that dropped to 0 after a water change would suggest the test kits are fine.

Don't bother going to the shop today. Do it tomorrow or whenever you can.

I would rinse the plants and then put them in the tank.

-----------------------
If the sand was from a pet shop it should be fine.

Was the rock and driftwood from the pet shop too?

-----------------------
At this stage I would monitor and hope the carbon absorbs anything in the water. See how they do over the next 24 - 48 hours and if more die, photograph them and let us know.

If it is poisoning of some sort, the carbon should help.

-----------------------
Your not adding any plant fertilisers are you?

Both lavarock and driftwood from same store.

I haven't been adding any fertilisers apart from once but then I realised it was pointless because the plants were already dead so have not added anymore since. This was mid cycle.
 
You've pretty much done all you can for now. Just monitor and hope the carbon works :)

I have contacted the guy who runs an independent fish store also near to my LFS. I sent him the pictures, relayed all the information to him and he says if my parameters are good, then he thinks it is gill flukes.
 
Gill flukes don't kill fish that quickly, and they cause the fish to gasp and struggle to breathe for weeks or even months before the fish dies. Your fish are breathing normally until a few hours before they die.

Just let the tank run and see if the carbon helps and let us know how they are tomorrow :)
 
Conflicting advice is confusing lol.
Either way I am back at work on Wednesday and on 12 hour shifts so might take my mind off things, but it does mean I'll be spending less time with the tank.
 
I managed to capture a video of a worm which eventually got pushed off the glass then buried itself in the substrate.

Probably harmless but no harm in posting;

 
that's a leech. it would have come in on the plants.

Check the other things on the glass and see if any of them look like long thin tubes with tentacles on top. These will be hydra.

Leeches don't normally affect fish but will latch onto and suck blood from fish if they can catch a fish. However, I doubt it is what has killed the harlequins. Hydra will eat baby fish but not adults.

How are the harlequins today?
Have any more died or are they still alive?
What's their breathing like?

-----------------
on a side note, if you turn your phone on its side, the video will fill up the entire screen and show the tank off better :)

Ah I see, horrible looking things lol!

I don't see any tentacles to be honest but these things are microscopic and I don't have a microscope at hand. I am not too concerned about the white things on the glass after reading up about it. I feel more relaxed about that now.

3 still remaining today, so I've named them Prawn, Smokey and Sausage after my breakfast lol
They look as active as ever and colour looks good. I haven't seen any reach for the surface although one does seem to have an obesssion with swimming up and down the glass in the corner maybe just seeing his reflection.
But they look good so far, will see how the day progresses. Should I feed them? They have only been fed twice since Thursday.

And since I am here, my plants have just arrived :)

Pic of the tank after putting the plants in:

And a wee video of the rasbora;
Water is still a bit cloudy as I've just put the plants in;

 
when did the last rasbora die?

The remaining rasboras that are swimming up and down the glass are trying to school with their reflection. When things have been good for a few weeks you can get them some mates to hang out with but not for a couple of weeks.

I would give them a small amount of dry food each day but not too much. Monitor them after you feed them and see if they breath heavily, they shouldn't.

It's been over 24 hours since the last one passed. the others are showing no signs that the deceased ones did.

I'm about to head to the LFS with my water sample. Be interesting to see what they say if nothing else.
