Next steps
Concrete changes, not "research more" filler.
- •Celebes Rainbowfish 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. Marosatherina ladigesi
Primary: species page on Sulawesi limestone-stream origin (which explains the hard alkaline water requirement) and the extended-fin display in males.
- Practical Fishkeeping. Celebes Rainbowfish Profile
Secondary: editor coverage of stocking, water chemistry, and the colour development that needs months of stable water.
