if the tank gets too much sun AND there is enough plantfood in the water - this water might get green. Resulting in 0 visibility.

You better keep the sun out of the tank.

Further it is warmer there, but that only implies other species kept.

The problem with Otocinclus is, they eat constantly. Until collected, and then they don't eat for a long, long while. Most often until they arrive in the aquarium of their buyer. Quite often, they develop a lethal condition from this starvaton. In other words, bought Otocinclus need to be fed as soo...

Hi, Right now very few it has been reticulary difficult for me to keep plants alive in this tank. I have tried elodeas, anubias, java ferns, java moss. The only one that last for some time is the java moss. I was thinking of adding some duckweed. I only keep the lights on 6 hours but maybe there's ...

The C paleatus are the only fish in your tank preferring cold water, and colder water can contain more oxygen than warmerwater. Further, a fish in warm water will need more oxygen than in cold water. That is, your C paleatus could very well be the most sensitive to low oxygen levels - even though Co...

I can only tell about Dutch shops: some treat their water in case the receive wild cought fishes, but even these will only sell from tap water tanks. A fish shop uses a lot of water (high denisty implies lots of waterchanges, mostly done automatically) and any other water than tap water would be ext...

I would assume C panda is in the top 10 in the Netherlands. You see them everywhere.

Further the dwarfs, C pygmaeus, are also very common here

Regardless how it is made, NO3- is NO3-. There is no way to find out how the molecule was made. However, if nitrates have been build up slowly, there could be a possibility that an nitrate-eater would be interested in the high nitrates. In case of a high nitrate condition due to adding KNO3, this is...

The fish mentioned, Oncorhynchus mykiss, Oncorhynchus tshawytscha, Salmo clarki, are all from the salmon family. When a student, I did some toxicity work on heavy metals (copper, cadmium) on fish (Oreochromis mossambicus). From the literature I remember (30 years ago) salmons are very much more sens...

In that case 19. Footprint is what counts, not liters.

Most likely a 40 * 40 * 40 cm tank. With a 0,16 square meters footprint.

I have no clue what a "smudge spot Cory" is, but I would assume you could keep some 20 4-5 cm Corydoras in such a tank, if these are the only fishes

As Darrel stated, on paper the nitrates should not be able to reach such a level.

The fish are doing great. That allows one, I´d say, to blame te measurement.

Nitrate tests really expire after a while. So even this, rather convenient, conclusion is defendable.

I would continue what you are doing.

The cubic inch Victor mentioned is 15,625 cubic centimeter. Assuming a fish weighing the same as the water it replaces (fish generally weigh a little bit more, but not much) Victor advises 4 grams of fisdh a liter. The oscas would weigh 50 grams each, the carp 700. That is, there was room for some 8...

Not being well educated into English names for fish, but I would assume "walking catfish" is Clarias. What is the Sharptooth catfish? It could be the Souyth African name for the same fish.

As I don't know much about Corydoras, and dislike looking at You Tube, I did not follow the link.

I did read, however, what you wrote.

I wonder wheter there are any books, after all, a book needs to be sold, and there are not thwat many people wanting a big - 30 cm, 1 foot, fish or larger. Now, what will a fish need to thrive? Room, food an perfect water. The latter will be the same whether the fis is 1 cm or 30, and therefore I wo...

You keep Cardinals in a tank for Synodontiws multipunctatus? Cardinals come from the Rio Negro, pH around 4. The can be kept at pH 7, but Tanganjica fish like a high pH 8.5 or 9. Far too high for cardinals. Or the other tetra´s shown Further, the wood in the tank might not be ideal. Wood lowers the ...

In the long run, C paleatus would want it colder than the other 2 species.

I never heard of pertassium permangenate

Are you certain it was not potassium permangenate?

I´m afraid this is a hard question, there is hardly any information regarding Glanidium in the Cat e log

Obviously, there mst be SOME reason this genus was erected, but I can´t tell you

I read It's just that as far as i can tell CO2 is not acidic until it dissolves in water. And I wonder, what is it that makes HCl acidic? It is that it reacts with water, resulting in H+ and Cl-, making the water acidic. That is, in most common practises, acidic Always means in relation to water. I ...
