The caves are great for my parrot fish when they wanna hide but the plant decorations on both I received were not glued on very well. One fell off right out the box and the other shortly after adding it to my aquarium.

Cave for blue

Poorly made. Paint chips off and the plants are hot glued onto the cave.

Not just for bettas or bottom feeders!

I keep Crayfish as pets and I can’t stress enough that it’s important to have places for them to hide! We’ve had this decoration for a few years and it’s seen it’s share of use by all the Crayfish I’ve owned, but I have a baby female Crayfish named Princess and she does go in it, but she’s so small, she’d prefer to hide amongst the cluster of plants we have towards the back of our tank. All in all, this cave decoration makes a great hiding place for any aquatic creature, be it a fish or a Crustacean!

I am cycling a new 2.5 gallon tank. I thought this would be a nice addition. I added it to the tank but I don't like for my tank. If I had a much bigger tank, it would be perfect. I am going to look for something else, and give this one away.

Nice Hiding Place

This is a nice cave for fish to hide under. I use it in a 20 gallon tank for my Loaches to hide under

Nice Little Cave

Good-sized cave with no rough edges - perfect for a betta fish tank. Can't wait to see how my little guy likes it when his big tank is ready!
