Re: Ottos

(Olga described her new Otto-type catfishes, which don't look like
each others)

There are about 20 species of Otocinclus catfishes, and about the
same amount of Parotocinclus spp, which are very closely related
to ottos.  Some ottos have the black stripe along their sides (like
tiny SAEs), some have small dark spots or dots.  Some are grayish,
some brownish.  They all are still "ottos", and they should eat
your algae.

and have been able to welcome the first brave spring birds, flowers
and butterflies.  Some snowdrifts still in shadowy areas.
