[quote=”7 Zwerge” post=3143]Hello you all!
Now I have another question:I´ve got my simoni simoni shrimps some time ago.
They seem to do well.Before I got the simoni, my friend “invaded” some red fire shrimps without much color, small and bigger ones, about 10 or 11, we think, in the dark water tank …
I cought most of them out of the tank before I set the simoni into the water ….
But I guess there still are left two or three or four, specially the smaller not coloured ones ;-( ….
Do you think they will disturb the simonis breeding with their pheromones?They won’t breed across the species the cross breed list say …[/quote]
They should be fine. I have simoni happily breeding in a tank with Neocaridina heteropoda (of which ‘red fire’ are a morph).
All next month (April).

[quote=”ourmanflint” post=2996][quote=”BigTom” post=2990]Stefanie I’m pleased to see your simoni doing so well. I tried them once in a tank with similar parameters to yours and found that they eventually died out. However my population has been living in hard water for a number of generations, so perhaps they no longer possess the same level of adaptation for soft waters.
I will give them another go though I think, just in case.[/quote]
Hi Tom
If you’re in the UK and know of anywhere I could also get hold of some Caridina simonii, I would love to try them with my Paro’s as well.
Cheers[/quote]
I don’t have huge numbers of simoni but if they do OK in the soft water tanks this time I can send a few your way. Have added some now so we’ll see how they get on. Mine came from Gerard (frothhelmet) over on UKAPS a while back so you could try asking him if you’d like some sooner.

[quote=”Peter Finke” post=2938]The only efficient medicine we know of is 2-amino-5-nitrothiazol, a yellow power, which was sold as “Hexa-Ex” (by Tetra) or Spirohexol (by JBL) in a pressed solid form.[/quote]
97% pure 2-amino-5-nitrothiazole powder is available from sigma aldrich in the UK and perhaps other scientific suppliers elsewhere –

Perhaps someone might be interested in purchasing and dissembling a quantity. I have not checked postage costs or any restrictions that may be in place.
There also appear to be several retailer sin the UK and Ireland still selling Spirohexol tablets –

I’m seriously thinking about setting some smaller tanks up for breeding, rather than just having the big tank. I’m not quite sure where i’m going to find the space though.[/quote]
Yeah the pH is coming down slowly as the percentage of RO goes up. I’ll probably hold it around 5 or so.
[quote=”Aleksandr” post=2919]Thank you Tom.
What kind of lighting?[/quote]There are three of these tanks all in a row with a single Hagen 36w T5HO unit suspended above to provide lighting to all three.
Hi Aleksandr. The tank is 25 litres (perhaps a little small for 2 pairs, but will do for now). The filter is what was in the tank already – a Dennerle ‘Eckfilter’, I have simply passed the outflow through the foam to create a mattenfilter, providing a large surface area for filtration, moss growth and perhaps microfauna. Already the fish seem to spend quite some time grazing on it.
Water stats are currently pH 5.6, 90µs and 24 degrees. I started the fish in tap water (as at the fish shop) and am performing frequent small water changes with RO to bring the numbers down gradually.
Just got a couple of slightly better shots of the colours of the males in an aggressive mood after feeding –
Thought that might be the case Peter. Will wait until they’re older but it’s hard not to play the guessing game as you see them develop!

A friend of mine has a similar tank with an acidic substrate and has successfully bred good numbers of Paros sp ‘Sentang’ and chocolate gouramis in it without any intervention
Hi Tom,
What water parameters in this tank? What specific substrate does he use?[/quote]From my friend –
“Kh was 0 and sonetimes 1, gh4 and ph tended to vary between 5.8 and 6. Temp was 26.
Substrate was the aqua pond soil with eheim peat pellets sprinkled on capped with tmc nutrasoil.”The “aqua pond soil” is this one – http://www.ebay.co.uk/itm/Original-genuine-AQUA-SOIL-formulated-for-your-pond-plants-20-Litres-/151225919051?_trksid=p2054897.l4275
Basically just a topsoil without added nutrients I think, it has negligible effect on water parameters.
[quote=”Little” post=2873]Welcome back … we indeed missed you in your absence. Paros or no Paros your tanks are amazingly beautiful. Did you reposition the tank? It doesn’t appear to be in front of the window any longer. I must now go and read you post on the other forum.[/quote]
Very nice welcome back on this board 🙂
Yes, the tank was moved form the window to against a wall – it was annoying not having window access in the summer, and this way it can be seen from 3 sides.
Yes, I believe that the main issue for Paros with this tank was simply the substrate (the pond soil used contained lime, which I did not realise at the time). A friend of mine has a similar tank with an acidic substrate and has successfully bred good numbers of Paros sp ‘Sentang’ and chocolate gouramis in it without any intervention –
So it is possible, although I agree with Peter that a more controlled approach is generally preferable and obviously the more demanding species would need more particular care.
Aha. I still feel bad about not succeeding with Paros on the first attempt – I think I was trying to achieve too many things at once really. The new setups are more focused.
If people are interested in the tank apart from the Paro angle then perhaps they might like to read the journal over on the UKAPS forum, where there is much more detail and will not clutter up PP with non-Paro content 🙂
Now there is a coincidence – a reply to this topic after nearly 2 years inactivity just as I come back to the forum!
Now, this tank did not work out as a Paro breeding project due to issues with water parameters. I still have two of the original Paros in a retirement tank, but unfortunately I lost the females before I could have a proper attempt at breeding. However, I have now just turned two of my 25l tanks back into a Paro project. One is stocked with 4 currently unidentified young Paros which had been languishing in my local shop for many weeks. The second will be stocked with one species from this list –
[i]Parosphromenus anjunganensis
Parosphromenus linkei
Parosphromenus ornaticauda
Parosphromenus parvulus
Parosphromenus opallios
Parasphromenus filamentosus[/i]These are what are available from my importer, I have yet to decide which one – any suggestions?
In the mean time, I have been breeding Sawbwa resplendens, Danio erythromicron and Petruichthys sp ‘Rosy’, which are the current occupants of the ‘Bucket’ (among others).
Here is a recent video of the current status of the tank for those interested –
