Next steps
Concrete changes, not "research more" filler.
- •Common Pleco reaches ~60cm: tank length and turning room matter more than the litre number. A tall, short tank of the same volume is not equivalent.
- 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.
- LiveAquaria. Suckermouth / Common pleco (Hypostomus plecostomus)
Primary: large-aquarium retailer care guidance for the common / suckermouth Hypostomus type; emphasises long-term size and need for a very large system.
- Planet Catfish. Hypostomus plecostomus (Cat-eLog species sheet)
Primary: hobby species sheet: identification pointers, size expectations, and import caveats for the name 'common pleco' in trade.
- FishBase. Hypostomus plecostomus
Secondary: natural distribution and maximum size in the wild; cross-check 'common plec' in shops, which is often a different Hypostomus altogether.

Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.
Profile data confidence: medium. Typical care sources — trade names for this fish get mixed up, so verify the ID before you buy.
