Multifasciatus shell dweller
Fine dark flank bars and a mostly plain head.
A tiny shell dweller that rearranges sand around its home.
- Adult length
- Up to 4.5 cm (standard length, without the tail fin)
- Water temperature
- 24–27 °C
- Lifespan
- 5–8 years
- pH
- 7.5–9
- Hardness
- 8–25 dGH
- Natural habitat
- Inhabits beds of empty snail shells, forming colonies with individuals using separate shells.
Small size does not remove shell-territory aggression; digging can bury plant roots.
Appearance and identification
The pale brown body carries many fine dark flank bars and a relatively plain head. Adult males are usually larger. Sand digging and shell territories are central to its behaviour.
Social behaviour and territory
Adults defend shell territories. A colony is not a conflict-free shoal; watch subordinate fish and keep a separation option.
Compatibility limits
Check hard alkaline water requirements and competing bottom territories for each companion.
Space requirements
A pair needs a 45 × 30 cm footprint and 30 cm height; a colony needs more space. Provide more shells than fish, spaced apart.
Aquarium environment
Leave open fine sand and shell zones; rooted plants may be uprooted or buried. Secure plants away from digging.
Diet and feeding
Use appropriately small live or frozen foods and accepted complete foods; confirm every fish feeds.
