Next steps
Concrete changes, not "research more" filler.
- •Boesemani Rainbowfish should be kept in a group of at least 6 for best health and behaviour.
- •Royal pleco reaches ~40cm: tank length and turning room matter more than the litre number. A tall, short tank of the same volume is not equivalent.

Primary: aquarium size, water chemistry, behaviour, and compatibility (URL verified in upgrade script; recheck if site content changes).
- FishBase. Melanotaenia boesemani
Secondary: taxonomy, distribution, and maximum length in nature; cross-check with aquarium import lines and measured tank parameters.
- Wikipedia. Melanotaenia boesemani
Secondary: general species context; verify all husbandry numbers against a dedicated aquarium care sheet and your test kit, not a single table row.
- LiveAquaria. Royal (L-191) plecostomus (Panaque-type care sheet)
Primary: retailer care profile for the trade 'royal' / L-191: driftwood, tank size class, and feeding; listing may use Panaque sp. (L-191) as well as nigrolineatus in other lines. Confirm L-number with the seller when dollars matter.
- Planet Catfish. Panaque nigrolineatus (Cat-eLog species sheet)
Primary: community species sheet: wood requirement, import size, and the usual 'royal plec' name confusion across Panaque spp.
- FishBase. Panaque nigrolineatus
Secondary: natural distribution and maximum size; L-number vs museum name is still a moving target in the trade.
