Ocean Max-Fine Tangaria Gravel 1–2mm

Ocean Max Fine Tangaria Gravel 12mm is a natural freshwater aquarium substrate made from small crushed rock, designed to look like a riverbed while staying safe for fish and plants.

What it is

Fine Tangaria (often linked to Tanganyika-style gravel) is:

• Natural crushed stone gravel (not dyed plastic)
• Grain size about 12 mm
• Light brown / beige / sandy natural colour
• Made to resemble lake substrates like Lake Tanganyika environments

Main benefits

• Fish-safe & smooth safe for bottom fish like corydoras and cichlids
• Natural look gives a realistic river/lake bed appearance
• Good plant support roots can anchor easily
• Good water flow doesn't compact as badly as very fine sand
• Easy maintenance can be vacuumed during water changes

Things to know

• Can trap dirt between grains (needs regular siphoning)
• May slightly affect pH depending on stone type (usually minimal)
• Not as soft as fine sand for very sensitive bottom feeders
• Should always be rinsed well before use

Where it's used

• Community freshwater tanks
• African cichlid tanks (Tanganyika-style setups)
• Planted aquariums (light to moderate planting)
• Natural aquascapes with rocks and driftwood

Simple comparison idea

• Fine sand (0.11mm): softer, best for corydoras
• Tangaria gravel (12mm): balanced, easier cleaning, more texture
• Coarse gravel (36mm+): more flow, less plant-friendly
