[Ebook] 500 freshwater aquarium fish – Cichlids – Altispinosa Ram (Microgeophagus altispinosus)
Slightly larger than its better-known closest relative, the Ram (Microgeophagus ramirezi), this beautiful and variable species also has a particularly striking dorsal fin when it is fully extended. Males have extended top and bottom caudal-fin rays and, generally speaking, brilliantly colored pelvic and anal fins.
