I just realized, back in March 2023, I begun a topic on the new version of this tank...
2nd : three Sleropage formosus "high back golden" . They are allowed in Switzerland, but veryyyyy difficult to find in Europe... that means, it will cost me a kidney and I will definitely need a CITES permit to import
Hi,
great to see this project continuing! With regards to the Asian arowana’s - maybe you can find some on
eBay Germany, there’s some serious shops on there who might be able to help you. Else I can ask around, drop me a pm if you like me to.

light is 3 LED Spots (6500 kelvin each, in 200, 150 and 100 W), switching on progressively from 06:30 to 08:30 and switching off on the same theme, 12 hours later. That means a "soft" morning light (reduced by the heavy green wall that filters the light power), a full light from 08:30 to 18:30, and then, progressively, a sunset.
