Actually there are 3 Redtails and they are all 3 feet and a bit more. 2 of which I got at under 2" in 2005. I have never had a Wels I believe the fish you are looking at is one of my Wallego leerichopper;1277126; said:With regards the huge catfish. I notice that 1 is a redtailed catfish from south america. I assume the other is Silurus Glanis AKa European Wels? Was it hard to acclimatise to the tropical temperatures in the tank?
