Gerald Bassleer (case #146) presents a fish-disease case about chocolate gourami (Sphaerichthys osphromenoides) suffering internal, encapsulated worm infections (metacercaria and nematodes) observed in wild-caught specimens. He describes visible aquarium symptoms (darkening, weight loss, fin clamping, some asymptomatic carriers), shows necropsy photos of encapsulated parasite larvae in liver and spleen, and explains that encapsulation limits treatment options. Practical guidance: euthanize severely wasting fish (using clove oil, quinaldine/brand names cited), consider antibiotics if secondary bacterial disease is suspected, improve husbandry (water quality, low stress, high-quality food), and feed his recommended product (Dr. Bassler Bivish Food Forte) for 20–30 days to support immunity. The video also promotes books and Patreon training for further learning.
