Waterflow for Kuhli-Loaches

[Weltenbumler]

Hi everybody,

I am planing a new tank for my Kuhli Loaches. The size will be 100x50x50 cm (250Liter).
They will be together with trigonostigma hengeli in the tank.
Now I have a question about the waterflow. In the current tank (120Liter)
I have a filter with 750 l/h flow, which I would like to keep for the new tank.
On some internet-pages I read, that some people keep their Kuhlis in tanks with strong waterflow.
Should I use an additional powerhead to create more waterflow ?
How do you keep your Kuhlis, with strong waterflows or not?
I have an Koralia Powerhead with 900 l/h waterflow, which I do not use now.
Would it be a good idea to put this in the new tank and place it near the ground?

Greetings Thomas

Hi,

I don't use very strong pumps, only Aquaballs because the filterhead is good to close out of the box. No "tricky" workings with gauze and tube pieces to secure the filter outlet. I've lost a few pangio who wants to visit the filter through the outlet. With the "EHEIM loach safe filter" no more as long as its closed.

Another reasen why I don't keep my kuhlis all the time with stronger water movement, is that I have a bit more margin to play with the setup. So I can easier raise the flow for a rainy saison e.g.

Cheers,
Thomas

Kuhli's don't require strong water flow like how some other loaches do.

Hi

Thank you for the information.

If it is not necessary, then I will plan the tank setup without
the aditional powerhead and only with the canisterfilter.

If they seemed to need it you could always add a PH later.

I aim for about 10 times the tank volume per hour, so a 250 liter tank would get filter and power heads totaling 2500 lph.
Note that this is just what the manufacturer says, not what the equipment really puts out.

Hi,

10 times the tank volume looks like a strong waterflow to me.
Maybe it also depends on what kind of "waterflow-producer" it is,
filter only, filter with additional powerhead and what kind of
powerhead used etc.

That is exactly why I asked this question, some people have strong
waterflow for their Kuhlis, and some not. But what is better / more natural ?

Of course I could start with a not too strong waterflow first, and then
start increasing it to see what happens and how the Kuhlis react.
Probably I will do it this way.

But I am still interrestet to know, how other people keep their Kuhlis.
What tank size and what waterflow, with additional powerhead or not ?

Thanks for your informations

Greetings Thomas

Hi Thomas,

I keep around 30 pangios (oblonga and striped) in a 75 gallon aquarium. The only filtration that I have on this tank is a RenaXP3 which is rated at 350g/h.

Previously, I kept all of them in a 30 gallon tank (36") with only a sponge filter and two corner box filters (air-driven) for filtration.

From what I've read, kuhlis in their natural habitat are found in leaf litter in slow moving water. Some people keep Indian almond leaves or oak leaves in their tanks for their kuhlis to enjoy.

My six kuhlis are in a 20 gal long, with 2 Aquaclear 30 filters plus a bubble wand. They also have their shelf-cave plus Indian Almond leaves.
