I filmed these two cool fish using my Fuji X10 (a little rangefinder compact). The tank with the
Hypostomus luteus was brilliant to watch; so much activity from the
Leporacanthicus cf. galaxias 'L240' and
Corydoras adolfoi.
H. luteus seems to be quite popular currently, but I don't think people will have seen or heard of
H. commersoni before.
