I think the bigger issue is non-native fishes that survive in your climate. But a carefull keeper should not have this problem except when he uses an outside pond. In the Netherlands we have some issues with escaped aquatic species (mostly crayfish, but also Misgurnus anguillicaudatus). Truly native ...

Although a lumper, I still don't understand why the family Hypopthalmidae was reclassified and included in Pimelodidae.
I have not seen many pictures of Hypopthalmidae and take it that scientists have found out that these fish have no internal fertilization (thus unable to fit into Auchenipteridae ...

Yup, do you accidentilly know what they are?

And about the Mbandata. It is an unindentified Syno probably caught near Mbandata, congo. It is very similar to S decora but mine are still small. I will make pictures after I catch them for iidetification.

Well, after Bas his comment I went ahead and just placed an airstone in the tank. The filter is now running in my new tank. And now I can only wait and see.

Thank you all for your usefull comments. Next time I will prepare myself better and buy a small sponge filter to do the job.

Unfortunately missing. I stored it in the basement for several years, so i could have known something would go wrong.....

I recently moved in with my girlfriend and for a couple of reasons I decided to buy a new tank (325 litres in stead of 200 litres). Because the existing filter has enough capacity i wanted to keep using that one and place it on the new tank. The only problem is that my fish should still stay in the ...

Nice, natural looking tank!

How was your experience with the skittishness of the Alestopetersius? Mine (i have a shoal of 7 males and 5 females) are extremely skittish and dissappear in a small corner of the tank as soon as someone approaches the tank. A shame, since they are beautiful animals. The ...

Jac, thank you!

Too bad. Unfortunaltely there is only a limited amount of time and space for the fishes. Maybe I should ask on some lesser specialised local fora.

Because I want to set up a more low-maintenance tank the following fishes are free for pick up in Wageningen, The Netherlands(I cant ship or bring):
5 Panaque maccus
2 Lasiancistrus tentaculus
6 Corydoras Aeneus
4 Nannostomus eques
1 Abramites

I don't need any money for them, only the promise of a ...

Ok, thank you!

Me in my natural biotope....

Hmmm, soon took me 2 years...

Some fish came and went, but at the moment the stocking is as follows:
5 Panaque maccus (possibly 1 or 2 are other maccus-like L)
2 Lasiancistrus L92(?)
8 Nannostomus eques
7 Corydoras aeneus
1 Abramites hypselonotus

I know that the Abramites ...

This girl (and her friend) was sold to me as L092 (sorry for the poor pictures):

I am under the impression that is probably another Lasiancistrus, as the fish do not have any ...

Thans for sharing (as a relative youngster). I wonder why so many aquarists are old rockers (with respect!!). Perhaps a matter of good taste

Hi Goldenfeather,
IIRC ammonia and ammonium are in a constant balance, ammonium turns into ammonia when the pH reaches above 7. And thus becomes poisonous. And most chemical tests measure both ammonia and ammonium because they are so similar and because of the balance. If you know the total value ...

I don't know, but a lot of the Xingu species are treathened by some dam...

Also a splitter (mostly).
Even if different populations/species look the same they can be very different in ecology/behaviour. This is more visible in birds where some species are very difficult to distinguish visually, but are obviously different species (behaviour/song). These different species ...

And it depends on what you feed aside from the wafers as well. In the end the total intake is what matters.

Whahaha, superb!!!! My housemates girlfriend was not so pleased when she found out I use our mugs to defry the frozen mosquito larvae.

Sounds like something to consider next time. The tank is a display tank, so messing the whole thing up is not something i really look forward to.

Thanks all for the quick replies.
The rams are F1, the bred ones are plain ugly to me. I am familiar with the stories of eating the eggs when there is too much stress. But they they defend the eggs fierce against the Panaques, and wave fresh water at the eggs. After the light go out, the eggs ...

My rams spawn about every two weeks, but the eggs never last longer than one night. I am quite sure my 5 P. maccus are the caviar-thieves. Is there a way to save the eggs (without needing an extra aquarium)?

Thanks in advance,
Thijs

Hi there,

A dutch team made a movie of a group of more than 30 Silurus glanis, some of them more than 2 meters, in the Maas river in the Netherlands.

Good to see that this species is recovering to pre-50s numbers. On the other hand: this will reduce my enhousiasm for swimming in ...

Holland reached the finals in 1974 and 1978 and lost both. That's why a lot of dutch people love to see Germany in the finals. We have some revenge to take upon our bigger brother (preferably to win in the 90th minute).

Thanx,
As a plant ecologist I should know. But history learned me to value practical expertise. Especially Darrels remarks are useful. Especially the Lemna are very yellowish, maybe I should do a conductivity test.

Too bad an aquarium good for the fishes results in such ugly yellowish plants....

Lately both my Limnobium and my Lemna started to grow slow. I used to remove loads of these every week. Now I only need to remove them every few weeks. Does this mean my N is decreased, or are there other possible causes (and is my duckweed filter defunct)? Limnobium and Lemna are my only plants.

Okay, time to keep my eyes out for some farlowella vittatus. I hope to post a picture of my tank soon, but the is pretty hard to see through all the wood ;)

And that was a very quick reply, thanks...
