You dont got a test kit? How long has the tank been cycling?
I would go with cherry shrimp as feeders. Thats what I am doing right now. Got a 10 gallon with about 36 shrimp in there now with 2 females holding eggs. I just got it set up about 2 weeks ago. Theyre easy to breed and take care of, they breed often too. These are gonna be snacks for my catfish.
Shrimp are slower and easier to catch, guppies might make it a job for your bichir to catch since bichirs are clumsy eaters.
