I was thinking about buying one? I am going to research them on the web, but would like to know any info you could tell me.
I am not sure I understand the reference to "warm" food, and in all honesty, a steady diet of rosy barbs sounds like a terrible diet for axies. There is no variation to provide a wide array of vitamins and nutrients. With any living thing, a variety of foods is extremely important.
The best food is the soft pellets that are sold to feed salmon in private ponds, etc. They also greatly enjoy redworms, I mean OMG do they love them, along with blackworms, bloodworms, shrimp pellets, the occasional guppy or ghost shrimp, and white worms or grindal worms can be fed as a treat.
You can also use soft trout pellets. They do not seem to care all that much for harder ones. I have some sinking reptile sticks and I have fed those also, they gobble them right up.
