Of the several common names for this beautifully marked species, the Purple-striped Sleeper Goby and Sleeper Goby or Gudgeon are the most appropriate; the connection with trout embodied in the others is misleading because there is none. The slightly smaller but equally beautiful M. adspersa, also known as the Purple-spotted Gudgeon (from eastern and southeastern Australia), has similar requirements but is less frequently available.
Other common names

- Males become aggressive and territorial during breeding; less so at other times.
- Livefoods preferred, but other diets accepted.
- Sufficiently spacious and planted, with open area and with strategically placed caves or shelters around which several males can establish territories. Neutral to slightly alkaline, hardish water preferred. Temperature range: 72-86°F (22-30°C).
- Eggs are laid in caves or on flat surfaces (including bogwood or even the aquarium panes) and are guarded by male. Hatching can take 5-9 days.
