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.

Mikrogeophagus ramirezi
German blue rams are one of the most beautiful dwarf cichlids, with iridescent blue and gold coloration, a distinctive black spot, and red-highlighted fins. Despite being cichlids, they are remarkably peaceful and make excellent centerpiece fish for planted community tanks. They do require warm, soft water and are more sensitive than typical community fish.
