Anyone have luck keeping clown loaches with their bichirs? I understand a large clown loach is fine but will smaller one likely become lunch if the bichirs are kept well fed? Experiences?
That's basically what the guideline is for all fish regarding polypterus. As long as the clown loaches aren't small enough to fit in the bichirs mouth you shouldn't have any problems.
That may be pushing it. I would say it would work with almost every other poly, but from whag I've seen juvi endlis are the ones that are most prone to take something down, or at least try.
