Hi Sasquatch

I have bichirs and I got them real small when they were 3.5 inches. 2 of them are polypterus senegalus and one real small one when she was 2 inch, but can't identify her species exactly.

In your 2 ft tank, it's ok when they're small but remember they need space. Unless u can house them in a larger tank later as they grow, otherwise, get some smaller fish suited to your 2'.
