Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Bristlenose Pleco can escape if harassed.
- Planet Catfish. Genus Ancistrus (bristlenose and relatives)
Supports: catfish care at genus/species level where a single binomial is unreliable.
- FishBase. Ancistrus cirrhosus (representative bristlenose)
Supports: taxonomy and wild maximum size — translate to tank stocking, not a target number.
- Seriously Fish. Aplocheilus lineatus
Primary: species page covering Indian/Sri Lankan range, predatory behaviour, jumping risk, and surface-dwelling habit.
- Aquarium Co-Op. Golden Wonder Killifish Care
Secondary: retailer care page on stocking (top-dweller-only setups, jumping lid requirement, live feed).
