I was expecting a cone that can be placed in the middle of the tank. But this one is not exactly circular cone but is a side piece with suction cups and attaches to the glass. Nevertheless, the quality of this piece is good and my discus fish used it immediately for the next spawn.
My Plecos took the cave within 5 mins of placing it inside the tank. I'll recommend this product for pleco and angel breeding. Thanks to Indiefur, I received these caves in perfect condition. Their service very good.
