Combined minimum footprint reference for these two species: about 80L (larger active fish often want more length).
Temperament gap (peaceful vs semi-aggressive) — needs space, structure, and careful observation, not a “drop and forget” mix.

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Bristlenose Pleco can escape if harassed.
- •Pea Puffer should be kept in a group of at least 6 for best health and behaviour.
- 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. Carinotetraodon travancoricus
Primary: aquarium size, water chemistry, behaviour, and compatibility (URL verified in upgrade script; recheck if site content changes).
- FishBase. Carinotetraodon travancoricus
Secondary: taxonomy, distribution, and maximum length in nature; cross-check with aquarium import lines and measured tank parameters.
- Wikipedia. Carinotetraodon travancoricus
Secondary: general species context; verify all husbandry numbers against a dedicated aquarium care sheet and your test kit, not a single table row.
