Catfish cave made of clay conical shape
The spawning cave is round in its basic shape and flattened at the bottom. Therefore it lies securely even on smooth ground without rolling away.
With these conically shaped front entrance burrows with the width continuously decreasing towards the back, pretty much every individual finds the right place to anchor in order to be able to fan the clutch from an optimal position.
We use stoneware clay for the production of our clay articles, which can be highly fired and contains a varying proportion of fireclay depending on the product.
On the one hand, this makes our caves very stable and durable. On the other hand, this means that the surfaces are never completely smooth, which provides an excellent basis for surface growth, which in turn is very readily grazed by the catfish.
This slightly rough surface of the cave also benefits the adhesive properties of most fish eggs without damaging the eggs. The eggs adhere better to the cave wall, minimising the risk of the eggs being flushed out of the cave.
Our large model is very suitable for Pseudacanthicus (L24, L25, L97 etc.) or Hemiancistrus subviridis (L200 LoFin).
