Forgot to mention: I paid 133,- Euro's for it. Prices for UV sterilizers go from approx 50 Euro's to very expensive. Apparently a lot of the cheap ones perform very poor and are only usable as clarifier and not as a sterilizer. It took me more than a day of checking out the internet to determine whi...

This is a bad weekend for my bank account! I ordered additional to th eabove protein skimmer and pump a "TMC Pro Clear Ultima 30 watt". Also this could help the TSN a little bit by improving the water quality. uvc-pro-clear-ultima-tmc-30-watt.jpg Also this I ordered with in mind my next en...

Pfffff…….. In situations where you do not see improvement in your pet you tend to spend money on things that are probably not going to solve the issue. But then at least you can say to yourself that you tried. So to make myself feel better I ordered a brand new freshwater protein skimmer including a...

A few LED’s compared to the other costs are not even on my mind. It’s more or less a “design” and “purpose” issue that light and plants are difficult. There is quite some (heat) lightning in the enclosure. But the issue is that the land area is above a big part of the water. Water surface is approx....

Oh,... forgot to mention. I have no idea how big he is right now but he is still visibly and significantly growing!

Small update: IMGP2651.JPG Have been changing water regular this week I still do not see signs of improvement or even changes at all. He is eating but in my opinion clearly not as he should. His body mass is more than just good and it looks he is gaining even more weight instead of losing weight. P...

Sorry for the people that do not like a lot of reading. For the ones that maybe can use the lessons learned out of this I write it as complete as possible. Hopefully this allows also others to provide advice. Status: The TSN is doing better but still not as he should. I reckon that there was an “esc...

Way to busy especially the coming days so in between I quickly went to the shop to buy the goods. Been slowing down with water changes since there was improvement. So approx. 60 hrs ago since the last time I have been changing water. I first measured the water again with a 6 in 1 JBL test strip. Bel...

Summary of loose things mentioned earlier in this topic. What will I /want to feed my TSN: 1) Whole frozen fresh water fish but fed in pieces. The fish are too big to be fed at once. I buy these fish in 10kg for approx. 23 Euro’s. Which is mega cheap. This is through a large trading company that als...

Update: Yesterday I fed the caimans. One of them ate nearly all so I tried if the other one wanted a rat pinky today. He was not interested. Was already some time ago since I tried feeding a baby rat to the TSN. I know and I agree it should mainly eat fish! He came straight away, checked it extended...

One of the warnings I find on he internet is that TSN often die because of that. I checked sturgeon and trout pellets and they most often have approx 19-22% oil/fat On a biological one it mentioned approx 11% raw fat. For Hikari Masivore, which is specific for e.g. red tail catfish that is not less ...

Unfortunately the TSN did not eat today. I do not think it had anything to do with vitamins or minerals. I left the piece in the water for 2 hrs in front of his nose but he didn't even checked it out. He has been eating three days in a row and yesterday a bigger piece. If he would have been healthy ...

Sorry no idea why the youtube video's don't work but clicking the link works for me.

Bas, I found the Sera vitamines. Somehow that did'n't pop up during my quick search. Small bottle only cost 7 euro's so low cost test. Was doing some quick research today on youtube on commercial farming of TSN. You won't find much in English but in Spanish there is some. Two links I like to share f...

It's indeed one of the pigeons films.
Thanks for the article! I will read later today.

Will try the syringe tonight and will tell how it went. But no specific fish vitamins and minerals are available on the market. At least a quick search didn't show anything. So this is no long term solution. I only used tried Tetra Cichlid Shrimp Sticks. These dissolve quick in the water. Will check...

Feeding today: I used a big piece of fish today that I sprinkled rich with minerals and vitamins on the outside. It sticks very well to the slime of the fish. After letting it dry for a while it sticks even when tossed in the water. I knew the change was high that most of the minerals and vitamins ...

Lycosid, thanks! You made me think and I now know what to do next. In reply to 1) Fully agree with that they mainly should eat fish and not terrestrial food. But large catfish are known to sometimes eat ducklings or rats as well if the opportunity is there. Intermezzo: Keeping crocodilians only make...

Thanks for the extended reactions! Current situation: Yesz…!!! Aldo the situation is nothing to cheer about I have a better feeling now it is starting to eat again. It ate yesterday a very small piece after a long time. Today it ate a small piece straight away and another small piece also after appr...

Thanks Bas! Well than I have sponsored JBL and additional junk in the cabinet. My thinking was that if you would follow the test procedure strictly and quick the pollution probably would be so low that this way would still give a good indication. To me water measurements are more about indications a...

Thanks I will check if I can purchase a kit like that somewhere in the Netherlands. Looks like the situation is possibly stabilizing but still too early to say. Haven't seen it scratching in the last two days anymore. But I can see that it still has scratched itself. In combination that it is hangin...

Viktor thanks for the reply. Good to know that they can fast for long periods. I do not measure NH3 & NH4. I have a six (6) in one (1) JBL Easy Test. Not the most accurate way to test water but considering my circumstances I thought good enough to get a decent understanding of the water quality....

I write below out to share my experience and because I urgently need advice! My Pseudoplatystoma Fasciatum that does not eat anymore and keeps scratching his head. See completely below "issue" description and "question". How I got my TSN Previous owner bought the TSN at 12 cm tog...

Jools and Bas, thanks for your answers!
30 years is a very long time. Respect!

I understood most catfish are from the wild and not bread at farms. Does this mean that there is a possibility that I can ask a seller/trader for a cites paper, which should indicate the place of where they are caught?

I often find it hard to know the length which a fish can become. Some species are given a length which is possibly a length which it gets in an average aquarium. So smaller then what it could become. Others are given max lengths measured in nature which you will hardly meet in captivity. Unfortunate...
