Species Profiles
Oscar Fish
Astronotus ocellatus
intermediateaggressive75+ gal
Oscars are large, intelligent South American cichlids often called 'water dogs' for their interactive personality. They recognize their owners, beg for food, and can be hand-fed. However, they grow fast, produce massive waste, and need at least a 75-gallon tank.

Panaqolus maccus

Clown plecos are beautiful, small plecos with striking orange and black striped patterns. At only 3.5 inches max size, they are perfect for 20-gallon and larger community tanks. Unlike many pleco species, they are primarily wood eaters rather than algae eaters — driftwood is an essential part of their setup. They are shy, nocturnal, and make excellent additions to planted tanks.
