Category: Aquarium Aquatic Aquascaping Botanicals

Add the perfect finishing touch to your blackwater aquarium with Turkey Acorn Cups. These small but highly functional botanicals are ideal for aquascapers looking to create a realistic forest-floor effect, mimicking the fine details found in natural riverbeds and flooded woodland habitats.

Despite their compact size, acorn cups release a surprising amount of beneficial tannins and quickly develop biofilm, making them a favourite grazing spot for Caridina and Neocaridina shrimp, as well as Plecos and Ancistrus. Their natural cup shape also provides excellent micro-hiding spaces for shrimplets and fish fry, helping to reduce stress and improve survival rates in breeding setups.

All Castle Dawn Aquatics botanicals are organically sourced, free from pesticides, and naturally sun-dried without the use of chemicals.

Victoria S. ★★★★★

These acorn cups are exactly what my blackwater tank needed to nail that forest-floor look. They sink quickly and held their shape well for weeks. The pack of 40 gives plenty of spares for my next rescape.

Thomas M. ★★★★★

My betta's been swimming through these Turkey Oak acorn cups like he's patrolling a little forest floor, and the tannins they release tinted the water a gorgeous tea color within a day. The 40-pack gives me plenty to scatter across multiple tanks without running out too soon, and they're small enoug

Daniel Z. ★★★★★

Dropped these into my blackwater tank and the tannin release gave the water that perfect amber tint I was after. The acorn cups are small enough to nestle between driftwood without overwhelming the scape, and they sink right away. My shrimp have already claimed one as a hideout.
