Fishes love it

This design looks great in my tank and my fish loves it. The fishes would swim in and out of it or just stay in it.

Aquarium Underground Cave Dome

Works great

Perfect for what we needed, and not flimsy. Our cory love it, and can now eat in peace. Our pig of a common gold fish hates it since he can't get in to eat their food.

Nice addition

Looks good in my aquarium and the fish seem to love it. Had one bigger fish squeeze in and couldn't get out. Had to save him, but kind of comical.

It fits nicely up against the glass, stays down in the substrate, the fish love it and it looks nice. Very pleased with this product.

Underground Natural Curve Double Hole Tunnel

Perfect for juvenile eel!

Our Indian Mud Eel loves it! We got it for him, took him a few days to find it, but once he did he claimed it for himself! Sometimes our African Knifefish shares it with him too. They love it! 😍

Fish love it!

I have a big Oscar in my tank, and my loaches love this hideaway! Pretty small, but truly the perfect size as a hiding place. Recommend!!
