Species Profiles
Otocinclus Catfish
Otocinclus spp.
Otocinclus catfish (otos) are tiny, peaceful algae eaters that are incredibly effective at controlling soft green algae and diatoms in planted tanks. They are the gold standard for planted tank algae control, often preferred over larger plecos. However, they are somewhat delicate and require established, well-maintained aquariums.

Trichogaster chuna
Honey gouramis are the gentlest gourami species — even more peaceful than their larger dwarf gourami relatives. Males display a warm honey-gold coloration that deepens to rich amber when breeding. At only 2 inches, they are perfect for nano community tanks. They are also significantly hardier than dwarf gouramis, which suffer from the iridovirus (DGIV).
