At the end of last year, I did fulfil a personal dream, and bought two little wels catfish. I ordered them together with several other coldwater fish from a fish farm. One is wild-coloured and was around 15 cm and one is hypomelanistic, with a white-pinkish colour, and was around 17 cm at the beginning. Sadly the wild-coloured one wasn´t doing well at first and had white spot disease just one day after arrival, and later also something like finrot. But now it is luckily doing very well, it´s in good condition and the fins have well healed. During the first months I kept them in a quarantine tank in a comparably cold room (it´s winter...), and I couldn´t see any growth during more than three months despite strong feeding. Since some time they are in a big 150 l tank, and it seems they already increased a bit in size, probably because the temperature in this room is warmer. I feed them mainly with sturgeon pellets which are rich in protein and they obviously like them. When it was still warmer, I fed them also with earthworms, which they attacked in very aggressive ways.
I will keep them as long as possible in the tank, but if they grow too big, they will get an own pond.

They are both doing well, and have also somewhat grown. However their growth is much lesser fast than I supposed, probably also because the tank is unheated, and was always below 20°C during the last months. It´s interesting that they swim a lot next to the surface when the lights are off, sometimes even breaking the surface with the upside of their heads or parts of their backs.
 
Es geht bestimmt gut. Die werden sehr gross wachsen....
 
Wurde kein problem sein. Zwischen kois und welse, habe ich keine zweifel.
