My latest set up for Caridina dennerli

**Broddan** · 11th Oct 2011, 08:09 AM

Hi!

Ive kept and breed cardinals for almost 2 years now. This is my second aquarium because i need more space for my cardinals.

So far I have been using tap water but when propagation has slowed down i now modify the water a bit in one of my tanks with cardinals. So far i cant see any diffrence and both tanks slowly gets bigger populations.

Aquarium: 92 cm 25 cm 30 cm
Filter: Air driven sponge and RUGF throu a canisterfilter.

Loved your tank!
Why is it so low?
Are the rocks covered with algae?
What do you feed them?

My first idea was that you had a low tank so that the light could create lots of algae for the shrimps

Can you share your watter parameters with us?

very nice tank. i wish to have a low long tank like this one for my shrimps

Thanks!

Shrimp usually live on the bottom and the Cardinals are extremely attached to the bottom and swim is extremely rare (it do happens sometimes) The aquarium is custom to fit perfectly in my shrimpcabinet and i cant se any use of having it taller.

Water volume is still relatively large to be a shrimp aquarium and as a bonus the light get near the stones (I'll admit that this was not calculated by me, but was a bonus) Yes there is a lot of green algae on the rocks.

Most of all, I think it looks good.

Different kinds shrimpfood, spirulina, freeze-dried brine shrimp and others- all in powder form. Sometimes i give a few larger bits near the front to give me a good opportunity to observ them and se how many is berried and so on.

Ive started out with tapwater and it has work good. Now am testing to modify the water a bit in another aquaria.
But in this aquaria water parameters is:
pH: 8-8.2
KH: 8
GH: 8
Conductivity ~ 380 microSiemens (This value is the one i reduces in another aquaria to compare)

I want to know how. PH is the high and constant.

Because I have had many problems with the PH.

Internet access is very beautiful. Placement of stone and wood, as well. It has dimension.

Thanks!

Im not sure what the question are?

pH is high because the airdriven spongefilter drives co2 out of the water and the crushed coral substrat helps to.

Thank you.

Just put the broken coral The PH add up. Yes or no.

Yes. The combination of my tapwater (around KH 8 GH 8) and coralcrush gives my a stabil pH at 8-8.2.

Thanks, Broddan, for sharing your set up with us! I really like the tank dimensions, as I agree that bottom surface is the most important think for the shrimp. My tanks also are more wider than higher.

Keeping the cardinal in tap water shows that you have very good water where you live. In my region, I had no luck with it (as I had unwanted parts as NO3). For how long did you cycle this tank before you put livestock in it? Do you think that dennerli always should be kept together with snails? And how often do you feed?

Good to have an expert to ask here
