Nicola Vaughan –
Added a Spiny Turbo to my 120-liter reef tank last month. It’s been actively grazing on algae on the live rock and glass. No aggression or disturbances observed. Works well with my clownfish and small corals. A reliable and quiet cleaner.
Liam James –
The snail arrived healthy and has been active since setup. It’s not aggressive and doesn’t seem to eat anything other than algae. I appreciate its quiet presence and the way it helps maintain cleanliness without stress to other tank inhabitants.
Anna Wright –
Great addition to my marine tank. The spiny shell is unique and the snail is very active in cleaning algae. I’ve kept it for over three months and it’s still thriving. No issues with compatibility or behavior.
