Great fit for my Bristlenose pleco. The 1.5″ square opening is just right, and the cave holds its shape well. No chemical smell or discoloration in the tank. Solid build quality.
Olivia Wilson –
Used this for my Hypancistrus and it’s been a perfect hiding spot. The material feels sturdy and doesn’t absorb water or stain the substrate. Easy to place in the tank.
Felicity Morgan –
Works well for small plecos. The square opening is a bit tight for larger fish, but ideal for the species it’s designed for. No issues with water quality or durability after a month.

Highly recommended for breeding setups. The stoneware material is non-toxic and doesn’t break even after repeated handling. My plecos use it regularly.
