I recently purchased 2 4" temensis, and was planning on using DMack's suggested method. I have to get them eating out of my hands first. In the mean time, I have been trying different foods just to see what they would take. Up until today they would only eat goldfish and frozen blood worms. They even spit out small night crawlers.
However, today when dropping in some Hikari sinking carnivore tablets for my catfish, one of my PBass decided to try the Hikari tablets, and he liked them! I was dropping them in one at a time, and watching them slowly sink.
The package says it has special attractants for carnivorous fish, so maybe this has something to do with him taking dry food. Anyway, I was quite supprised. I will post an update if I can get my other PBass to take these tablets too, and wheter I have continued success with the first PBass.
Maybe this stuff is worth a try if you want to get them eating pellets/tablets.
I still plan on using DMack's suggestion to get them to take krill, and plan on using the same method for earth worms.
