Giant danios might be ok, no no to cardinal since they are to small, even a 4” senegal can eat them.
It won't be 3 inches forever. Those tetras will be snacksThe pieces of tilapia I give him are about a third or half the size of a tetra but he still struggles to swallow them whole. In fact I worry he'll choke every time I feed him but I can't cut the tilapia any smaller without it turning into mush. He's barely 3 inches long.
the big problem with feeders is most of the time people don't quarantine them and that is when disease can be passed along. That is why I breed my own for my butis butis. Another problem with feeders is if you just throw them in they are usually aren't very nutritious since they have been fed the cheapest of cheap food, but if you are feeding them a good food those nutrients are transferred to the predator and this is called gut loading. So long story short it should be fine if you are feeding properlyI have the Aquaclear running on another tank I'm cycling right now and its filled to the brim. Its still loud enough to be annoying at night. Probably because the tank is right behind my bed, lol!
What about dither fish? I'm thinking of getting some cardinal tetras or danios for now. I'll move them to another tank once the bichir gets large enough to eat them, but if he does happen to eat one before I do so, what are the chances he might get parasites? I know feeder fish are notorious for them. What about tetras and danios?
what I do with the tilapia is run it through a food processor it clumps together and even the smallest bichir can tear a piece offThe pieces of tilapia I give him are about a third or half the size of a tetra but he still struggles to swallow them whole.

Thats is normal, most small polys will do that, the tilapia will soften after a few min in the water, poly wont have problem swallowing it.The pieces of tilapia I give him are about a third or half the size of a tetra but he still struggles to swallow them whole.
