Ah, I see, Helene.

These are peat fibres.

If we use the word sphag­num in Ger­man, we talk about the liv­ing green moss — which later decom­poses to peat. I was inter­ested in using it in an aquarium.

Sphag­num is the latin name of the most impor­tant genus of peat-​building mosses in the north­ern Euro­pean and Amer­i­can bogs. Ste­fanie obvi­ously did not think of peat but of liv­ing plants that grow in peat ditches and built our peat over thou­sands of years.

It’s good an idea since Sphag­num needs very acid envi­ron­ments with rather low pH sim­i­lar to those in the home­lands of our fish. The only prob­lem I see is tem­per­a­ture. I do not know whether Sphag­num tol­er­ates higher tem­per­a­tures. I tol­er­ates very low tem­per­a­tures since it exists in the north of Nor­way and equally in north­ern Canada. Unfor­tu­nately I do not know what it’s south­ern bor­der is. There might be a need for high con­cen­tra­tions of oxy­gen bound to those low tem­per­a­tures, but that should be tested. Another prob­lem could be light. Liv­ing Sphag­num needs much light. It is con­stantly grow­ing at the upper­most end, the sur­face of the wet peat, and it imme­di­ately dies to peat if over­grown by itself. In the case of dying it lacks light and it does not need it any longer, but liv­ing it needs a great amount of it. One must try.

We do use some Euro­pean plants in or near the water in trop­i­cal aquaria that nor­mally do not live in coun­tries with higher tem­per­a­tures, for instance Lysi­machia num­mu­la­ria or Hot­to­nia palus­tris. Maybe our Sphag­num stands it, maybe not. But equally other Sphag­num species may exist in the home­lands of our fish, too, par­tic­i­pat­ing on the peat build­ing processes over there. Is there any­body here who knows? It would be not aston­ish­ing that the aquar­ium trade has not dis­cov­ered them as Aquar­ium plants for they would be use­less for the stan­dard aquar­i­ums and with­out use com­mer­cially. They really need very low pH, do not only stand it.

Well, one should have a try. But you may not remove those plants from Nature reserves; it’s rightly for­bid­den. Try to find a region where this is pos­si­ble with­out harm­ing the biotope.

I thought it was time for a lit­tle update on this par­tic­u­lar tank. It has now been run­ning for around four months and every­thing is going well.

There are times when I won­der, how many fish is in there still, — are they all there ?
It clear to me that they have split the tank in two major ‘areas’ — and two dom­i­nant males have found my pre­placed caves. So there are two males, one in each side of the tank, — some females very clearly ‘belong­ing’ to one of the caves, always around the same area, — and then there are som ‘loose’ fish, a few less dom­i­nant males and a few smaller females. They occupy the main area of the tank, sneak­ing around under­neath the leaves.

If I feed with moinas sud­denly there are many fish in there :)

One day I found out that there were two lit­tle fry swim­ming. I have posted pho­toes in another thread, but will post them again here.
Since that day I have counted at least 5 fry. That is a sur­prise to me that they spawned in there. Since then I have added 20 boraras. This may of course mean there will be no more or less fry, — but then that will have to be. It was never intended to be a breed­ing tank. And I am actu­ally not so sure boraras are a big thread to fry ? They dont seem to move in those areas of the tank where I would think fry is mov­ing.

Here some pho­toes of one of the males, the fry and one of the big­ger females.

Helene, nice pho­tos! (Hope I will see some of these nice mini-​nagyi in my tank too, one day)
For me it’s very inter­est­ing that it goes that well — so many fish of one species in one tank, and they’re breed­ing! What you tell doesn’t sound as if there was much aggres­sion?

Con­cern­ing the Boraras .….….… I think they are real “fry-​catchers”. I have B. mac­u­la­tus in my Badis kan­a­bos tank — and I had a lot of fry when the pair was alone. Since I put the Boraras in that tank, there are only very few fry — although the male Badis is breed­ing .… and breed­ing .… and breed­ing .… I am not wor­ried about this, because I still have more fry of Badis kan­a­bos than inter­ested aquar­ists .… But never trust the Boraras .….…
