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.

Puntius titteya
Cherry barbs are one of the most peaceful barb species, making them ideal for community tanks. Males develop a deep cherry-red coloration when mature and in breeding condition, while females remain more subdued with brown-pink tones. Unlike their more boisterous relatives like tiger barbs, cherry barbs are gentle, shy, and compatible with even the most delicate tank mates.
