Otocinclus Catfish Care: Size, Food & Water
It is often said that Otocinclus Catfish care is relatively easy. But while care should be easy and straight foreword, keeping Oto Catfish can be tricky because they a delicate freshwater aquarium fish. Otto Cats often die shortly after being added to an aquarium, even after appearing to be healthy, active and feeding well during the first few days. That said, some can live over one year and grow in size…under the right conditions and with a little luck.
In terms of Otocinclus Catfish care, Ottos should be added to a well established , mature, stable and clean aquarium in order to allow them the greatest chance of survival.

Some Otocinclus will eat green zucchini slices and some will not, so try it out for a few days. If the Ottos do not appear to be interested, take the zucchini out of the tank before it decomposes, disintegrates and creates water quality issues.
